+# NATS cluster message speed
+
+Run **`20260912T045131Z`** (UTC). Client: LXC **510** `verae-px-worker` (`10.10.10.20`), not a nats-* server. Servers: `nats-a/b/c` on `10.10.10.21–23` (`vmbr1` only).
+
+Client URL:

+
+## Method
+
+- **Core NATS** is fire-and-forget pub/sub (`nats bench`). No disk, no replica ack.
+- **JetStream** uses **file** storage and **replicas=3** (same as product streams). The unique stream `benchstream` is deleted between JS loads.
+- Throughput is **msgs/sec** from nats CLI **0.1.6** (`--no-progress --csv`). Its min/avg/max are publisher **rate spread**, not delay.
+- **Ping** delay: one publisher, sequential publish-then-wait. This is one-message round-trip through the cluster.
+- **Flood** delay: N publishers dump the whole batch, then the subscriber drains. This is **queueing under burst**, not wire RTT.
+- Probe: `scripts/latency.mjs` (two connections, header timestamp).

+## What the numbers mean
+
+Product job/event/archive traffic is **JetStream r=3 file**. On this three-LXC stand that is about **16k durable 128 B pubs/s** (about **13k** at 1 KiB). Core NATS is an upper bound for non-durable fan-out: about **0.7–2.0M msgs/s** aggregate at 128 B, or **~630k msgs/s (~616 MB/s)** at 1 KiB with 4 publishers.
+
+A quiet request-reply is **~0.3 ms** average, **p99 < 1 ms**. Flood rows in the **150–500 ms** band are the subscriber catching up after a burst, which is what a job-events mailbox sees if publishers outrun consumers.
+
+Re-run on NS1: `bash scripts/bench.sh`. Raw logs/CSVs are under `results/<utc>/`.

+Three **distinct Proxmox LXC** guests running **NATS JetStream** as a cluster, on the private bridge only. This is the test stand before the same layout moves to separate hardware.

+**Not** on `vmbr0`. **Not** `0.0.0.0`. Host lab NATS on `127.0.0.1:4222` is left running so current keep/fleet/middleware stay up until you cut over.

+# 1) create product streams (replicas=3)
+bash scripts/ensure-streams.sh
+# 2) fleet overlay nats.url + services/*.json already list the three URLs
+# 3) restart fleet and keep with NATS_URL from client.env
+```
+
+`JETSTREAM_REPLICAS=3` on middleware. Host `127.0.0.1:4222` can stay up unused. Zapier cloud never talks to NATS.
+
+nkeys/mTLS: `verae-nats-accounts` still has the INTERNAL/LEAF sketch. Do **not** enable accounts on this cluster until every client passes credentials in `NATS_URL`. Private `vmbr1` is the current isolation.
+
+## Message speed (throughput + delay)
+
+From a **client that is not a nats-* server** (LXC 510 `verae-px-worker`):
+
+```bash
+# on NS1 (hypervisor). Bench client is LXC 510.
+bash scripts/bench.sh
+
+# Full study that must run ON NS1 (orchestrator + charts + HTML/PDF):
+bash scripts/study-on-ns1.sh
+
+# Maximize cores/RAM + tmpfs JetStream, same ladder, restore ZFS after:
+bash scripts/maximize-ns1-study.sh
+
+# Exhaustive factorial (r=1/r=3, file/memory, reconnect, UDP, MQTT) + combined report:
+bash scripts/exhaustive-ns1-study.sh
+```
+
+That writes `results/<utc>/` and copies a summary to [BENCH.md](BENCH.md). Full write-up with charts (HTML + PDF) is in the progress repo: [nats-cluster-bench](https://zapier.georgelambert.org/packages/zapier-decisions/reports/nats-cluster-bench.pdf). Core NATS is fire-and-forget; JetStream rows use **file** storage and **replicas=3**. Ping delay is sequential RTT; flood delay is queueing under burst.

+Proxmox LXC 511–513 (`nats-a/b/c`) form a JetStream cluster on `vmbr1` for HA testing before dedicated hardware.
+
+Message speed (client LXC 510 vs the three nodes): see [BENCH.md](BENCH.md). Product streams are JetStream **file + replicas=3** (~16k durable 128 B pubs/s on this stand). Core NATS is ~1–2M msgs/s at 128 B. Sequential RTT ~0.3 ms; flood queueing is hundreds of ms.

+# NATS cluster message speed
+
+Run **`20260912T051237Z`** (UTC). Client: LXC **510** `verae-px-worker` (`10.10.10.20`), not a nats-* server. Servers: `nats-a/b/c` on `10.10.10.21–23` (`vmbr1` only).
+
+Client URL:
+
+```text
+nats://10.10.10.21:4222,nats://10.10.10.22:4222,nats://10.10.10.23:4222
+```
+
+## Method
+
+- **Core NATS** is fire-and-forget pub/sub (`nats bench`). No disk, no replica ack.
+- **JetStream** uses **file** storage and **replicas=3** (same as product streams). The unique stream `benchstream` is deleted between JS loads.
+- Throughput is **msgs/sec** from nats CLI **0.1.6** (`--no-progress --csv`). Its min/avg/max are publisher **rate spread**, not delay.
+- **Ping** delay: one publisher, sequential publish-then-wait. This is one-message round-trip through the cluster.
+- **Flood** delay: N publishers dump the whole batch, then the subscriber drains. This is **queueing under burst**, not wire RTT.
+- Probe: `scripts/latency.mjs` (two connections, header timestamp).
+
+## Throughput

+## What the numbers mean
+
+Product job/event/archive traffic is **JetStream r=3 file**. On this three-LXC stand that is about **16k durable 128 B pubs/s** (about **13k** at 1 KiB). Core NATS is an upper bound for non-durable fan-out: about **0.7–2.0M msgs/s** aggregate at 128 B, or **~630k msgs/s (~616 MB/s)** at 1 KiB with 4 publishers.
+
+A quiet request-reply is **~0.3 ms** average, **p99 < 1 ms**. Flood rows in the **150–500 ms** band are the subscriber catching up after a burst, which is what a job-events mailbox sees if publishers outrun consumers.
+
+Re-run on NS1: `bash scripts/bench.sh`. Raw logs/CSVs are under `results/<utc>/`.

+**Progress report (second study)** · run `20260912T051237Z` (UTC)
+
+> **Execution provenance.** Every process for this study ran on **NS1.GEORGELAMBERT.ORG** (`70.88.205.138`): the orchestrator (`study-on-ns1.sh`), `nats bench`, `latency.mjs` (inside LXC 510 on this hypervisor), charting (`matplotlib`), and HTML/PDF (`pandoc` + `weasyprint`). The operator laptop did **not** publish, subscribe, draw charts, or render the PDF. Traffic stayed on `vmbr1` from LXC **510** to `nats-a/b/c` (**511–513**).
+
+This is a full methodology write-up plus the numbers from that on-host run. The earlier report (`nats-cluster-bench`, run `20260912T045131Z`) used the same cluster but was **orchestrated and rendered off-box**. Use this document when you need “it was all run on 138.”

+
+## 4. Study methodology
+
+### 4.1 Question
+
+On the NS1 test stand, what message **throughput** and **delay** does the three-node `verae` JetStream cluster deliver at several loads, and which part of the stack is the limiter for product traffic (jobs, events, webhooks, archive)?
+
+### 4.2 Hypotheses (stated before the run)
+
+1. **H1 — Core vs JetStream.** Fire-and-forget core NATS is at least an order of magnitude faster than JetStream **file + replicas=3**, because durable publish waits for a majority disk replica.
+2. **H2 — JetStream parallelism.** Adding publishers does **not** linearly increase JetStream write rate once the replica log is saturated.
+3. **H3 — Quiet delay.** Sequential pub→sub round trip on `vmbr1` is well under 1 ms p99 when the consumer is waiting.
+4. **H4 — Burst delay.** If publishers dump a batch before the subscriber drains, observed delay is **queueing time**, roughly linear in backlog, not in cluster hop count.
+5. **H5 — Payload.** Moving 128 B → 1 KiB lowers message rate and raises byte rate on core NATS; JetStream in this size band stays replica/fsync bound.
+
+### 4.3 Independent variables (what we changed)
+
+| Factor | Levels |
+|--------|--------|
+| Transport | Core NATS pub/sub vs JetStream file replicas=3 |
+| Publisher count | 1, 2, 4, 8 |
+| Subscriber count | 0 (JS publish-only), 1, 2, 4, 8 |
+| Message count | 1k, 5k, 10k, 20k, 50k, 100k, 200k (by ladder step) |
+| Payload | 128 B, 1024 B |
+| Delay mode | **ping** (publish, wait, repeat) vs **flood** (publish all, then drain) |
+
+### 4.4 Dependent variables (what we recorded)
+
+| Metric | Instrument | Unit |
+|--------|------------|------|
+| Publish rate | `nats bench` 0.1.6 Pub stats | msgs/s, MB/s |
+| Subscribe rate | `nats bench` Sub stats | msgs/s, MB/s |
+| Aggregate | `nats bench` NATS Pub/Sub stats | msgs/s (fan-out counts both sides) |
+| Publisher spread | nats min/avg/max **msgs/s** | not delay |
+| One-way-ish RTT | `latency.mjs` header timestamp | min, avg, p50, p90, p99, max |
+| Host load | `/proc/loadavg` before and after | load average |
+| Broker counters | `http://127.0.0.1:8222/varz` inside each nats LXC | connections, in/out msgs, cpu, mem |
+
+**Important:** nats CLI 0.1.6 min/avg/max are **rate spread across publishers**, not microseconds of delay. Delay is only `latency.mjs`.
+
+### 4.5 Controls and constants
+
+- Cluster name `verae`, three routes, client `:4222`, cluster `:6222`, monitor loopback `:8222`.
+- Client URL always the three-node list on `vmbr1` (never host `127.0.0.1:4222`, never `vmbr0`).
+- Bench client is LXC **510**, not a nats-* server.
+- JetStream bench stream name `benchstream`, **file** storage, **replicas=3**, deleted between JS loads (`nats stream rm --force`) so names do not collide.
+- Product streams were **not** the bench target (no load test on `ZAPIER_*` / `VERAE_ARCHIVE`).
+- No TLS, no nkeys, no account isolation (isolation is `vmbr1`).
+- Same nats CLI version (0.1.6) and `nats@2` Node client as the first ladder.
+
+### 4.6 Procedure
+
+1. Confirm this script is executing on **NS1.GEORGELAMBERT.ORG**. Refuse otherwise.
+2. Snapshot host load, memory, LXC configs, and each nats `varz`.
+3. From NS1, `pct exec 510` the core ladder (1p1s, 4p4s, 8p8s at 128 B; 4p4s at 1 KiB).
+4. Delete `benchstream`; JS ladder (1p, 4p, 4p×1 KiB, 2p2s pull) at replicas=3 file.
+5. Copy `latency.mjs` into 510; ping then flood at several batch sizes.
+6. Snapshot host/`varz` again.
+7. Parse logs on **this host**; draw charts; write HTML and PDF on **this host**.
+
+No publish, subscribe, chart, or PDF process runs on the operator laptop for this study.
+
+### 4.7 Instrumentation path
+
+```text
+[NS1 host 70.88.205.138]
+   study-on-ns1.sh  (bash + python3)
+        |
+        | sudo pct exec 510
+        v
+[LXC 510 verae-px-worker 10.10.10.20]
+   nats bench / node latency.mjs
+        |
+        | NATS client protocol to
+        v
+[LXC 511/512/513  10.10.10.21-23 :4222]
+   nats-server -js  cluster routes :6222
+```
+
+The hypervisor issues the guest commands. The messages themselves never leave `vmbr1`.
+
+### 4.8 Threats to validity
+
+| Threat | Effect on numbers |
+|--------|-------------------|
+| **One physical host** | Three “replicas” share CPU, memory, and usually the same datastore. This measures process/LXC HA, not disk HA. |
+| **Shared load** | NS1 also runs Caddy, Forgejo, keep, fleet, portal, and other CTs. Load average during a run is part of the result, not noise to ignore. |
+| **Single bench client** | All publishers live in 510. Per-publisher rate spread is contention in that guest. |
+| **Short runs** | Seconds of traffic. No compaction, no multi-hour page-cache eviction, no snapshot during load. |
+| **No TLS/nkeys** | Production auth will cost CPU. Do not treat these rates as post-nkeys rates. |
+| **Fan-out aggregate** | Core aggregate msgs/s counts pub+sub. Do not compare that column to JetStream unique writes. |
+| **Flood ≠ RTT** | Mixing flood averages with ping p99 produces a fake “NATS is slow” story. |
+| **Lab only** | Not a Zapier HTTPS bench and not live `api.veraetime.net`. |
+
+### 4.9 Ethics / safety
+
+Bench uses throwaway subjects (`bench.core.*`, `bench.js.*`, `bench.lat.*`) and a throwaway stream. It does not purge product streams. Zapier cloud has no NATS socket.
+
+---
+
+## 5. Suggestions for fine-tuning
+
+These follow from the method and from the first ladder on this stand (JetStream ~16k durable 128 B pubs/s; ping ~0.3 ms; flood hundreds of ms). Apply in order of leverage. Re-run **this NS1 study** after each change so the delta is measured the same way.
+
+### 5.1 Treat JetStream as the product limiter
+
+Product jobs/events/webhooks/archive are durable. Tuning core NATS to 2M msgs/s will not move a timestamp Zap. Put effort into **replica write path** and **consumer lag**, not core fan-out.
+
+### 5.2 Split storage class by stream
+
+| Stream | Suggested store | Why |
+|--------|-----------------|-----|
+| `ZAPIER_JOBS` | file, r=3 | Work queue; lose-a-job is bad |
+| `ZAPIER_EVENTS` | file r=3, or memory r=3 if events are rebuildable from job status | Hot waiters; measure both |
+| `ZAPIER_WEBHOOKS` | file, r=3, workqueue | HTTPS to Zapier is the slow consumer |
+| `ZAPIER_USAGE` | file, r=3, limits + max-age | Telemetry |
+| `VERAE_ARCHIVE` | file, r=3, on the **best disk** | Puts are larger and must survive |
+
+Try `ZAPIER_EVENTS` as memory store in a maintenance window and re-run only the JS + ping/flood steps. If ping stays ~0.3 ms and durable events still ack at a higher rate, keep it; if a CT restart drops in-flight waiters, revert.
+
+### 5.3 Give JetStream real disks
+
+Today r=3 on three LXC guests on **one Proxmox host** is three files, one failure domain.
+
+- Bind-mount a distinct SSD/NVMe (or ZFS dataset with its own vdev) into each nats LXC `store_dir`.
+- Set `sync: always` only on archive if you need it; default sync is often enough for jobs and is faster. Measure.
+- Do not put JetStream `store_dir` on the same busy rootfs as Forgejo/Caddy if we can avoid it.
+- When moving to three metal boxes: same configs, private NIC, one disk (or mirror) **per node**. That is the first change that makes r=3 mean “two boxes can die.”
+
+### 5.4 Isolate the nats CTs from the rest of NS1
+
+Host load on this box is often already several. Pin:
+
+- `nats-a/b/c`: dedicated cores, no steal from keep/fleet Node processes.
+- Memory high enough that file-backed streams stay cache-hot for the working set.
+- `cpuunits` / cpuset in `pct config` so a Zapier-facing Node GC pause does not stall fsync.
+
+Re-run this study after pinning; H1/H2 should move more than ping.
+
+### 5.5 Consumer and mailbox tuning (delay H4)
+
+Flood delay is backlog / consume_rate. Fine-tune the **waiters**, not the broker RTT.
+
+- `jobs.events` and `webhooks.deliver`: raise `max_ack_pending` so a slow HTTPS hook does not stall the whole consumer; cap it so a poison message cannot unbounded-buffer RAM.
+- Pull consumers: larger batch, shorter `expires`, more pullers horizontally (fleet replica floors) instead of one fat subscriber.
+- Middleware should **not** flood-publish then wait; it already does per-job publish. Keep that. The flood test is the outage profile when a consumer is stopped.
+- Alert on **consumer lag** (pending + ack pending) from JetStream, not on ping RTT.
+
+### 5.6 Publisher-side batching in middleware
+
+A timestamp job is one small JSON. 16k msgs/s is ample. Still:
+
+- Avoid per-byte publishes; one message per job/event.
+- Reuse NATS connections (connection churn showed up as publisher spread in the core 4p/8p runs).
+- Idempotent `msg id` / duplicate window sized to Verae retry window, not default-only.
+
+### 5.7 nats-server knobs worth measuring (A/B with this script)
+
+| Knob | Why try it |
+|------|------------|
+| `max_payload` | Keep default unless archive puts grow |
+| `write_deadline` | Slow consumer protection for webhooks |
+| `max_pending` | Bound memory on a stuck Zapier hook |
+| `max_connections` | Fleet workers + keep + middleware |
+| JetStream `max_file_store` / `max_memory_store` | Prevent one stream from filling the CT |
+| `max_outstanding_catchup` | Replica restart after a nats-c blip |
+| GOMAXPROCS = LXC cores | Do not overthread a 2-core CT |
+
+Change **one** knob, re-run `study-on-ns1.sh`, compare JetStream 1p 128 B and ping p99.
+
+### 5.8 Network
+
+- Keep NATS off `vmbr0`. No change.
+- When on metal: dedicated NIC or VLAN for cluster `:6222` vs client `:4222` if possible (replication vs client load).
+- Check virtio queue counts on the LXC nics if core 1 KiB byte rate plateaus.
+
+### 5.9 Security cost (when nkeys/mTLS flip)
+
+`verae-nats-accounts` is still a sketch. Enabling accounts will add CPU on publish. Budget: re-run this exact study **after** creds are in every `NATS_URL`, and accept a drop on both core and JS. Do not flip without that measurement.
+
+### 5.10 Operational fine-tuning (lag, not peak msgs/s)
+
+1. Scrape `varz` / `jsz` from the host over `vmbr1` (not public). Monitor loopback `:8222` is invisible to Prometheus on NS1 unless we add a host-side proxy on `10.10.10.21:8222` bound only to `vmbr1`.
+2. Keep replica floors for webhook-deliver and job-poller — they are the flood defense.
+3. Backup/restore drill of JetStream **during idle**, then a short JS 1p run to see catchup cost.
+4. A 15–30 minute soak (not in this ladder) for page cache and compaction; add that as a third study when disks are dedicated.
+
+### 5.11 What not to tune
+
+- Do not chase core 8p8s aggregate. It is fan-out on a lab bridge.
+- Do not treat flood 400 ms as “cluster RTT.” Fix consumers.
+- Do not load-test on `ZAPIER_*` streams.
+- Do not bind client NATS to `0.0.0.0` on `vmbr0`.
+
+### 5.12 Recommended next experiments (same method, one change each)
+
+1. CPU pin nats-a/b/c → re-run JS 1p + ping.
+2. `ZAPIER_EVENTS`-shaped memory stream vs file (throwaway stream, same flags as this JS ladder).
+3. Distinct `store_dir` disks per node.
+4. nkeys on, same ladder.
+5. Three hardware boxes, same `cluster.env` IPs updated.
+
+Each experiment should produce a new `results/<utc>/` on NS1 and a new progress-repo report so we can diff H1–H5 instead of arguing from memory.
+
+
+---
+
+## 6. Reproducing this study
+
+On **NS1 only**:
+
+```bash
+cd ~/verae-src/verae-nats-cluster
+bash scripts/study-on-ns1.sh
+```
+
+The script exits if `hostname` is not NS1. Outputs land in `results/<utc>/` including `nats-cluster-bench-ns1.{md,html,pdf}` and `charts/`. Copy those into `zapier-decisions/reports/` for the progress repo and catalog.
+
+Raw logs for this run: `results/20260912T051237Z/`.

+# NATS cluster message speed
+
+Run **`20260912T053120Z`** (UTC). Client: LXC **510** `verae-px-worker` (`10.10.10.20`), not a nats-* server. Servers: `nats-a/b/c` on `10.10.10.21–23` (`vmbr1` only).
+
+Client URL:
+
+```text
+nats://10.10.10.21:4222,nats://10.10.10.22:4222,nats://10.10.10.23:4222
+```
+
+## Method
+
+- **Core NATS** is fire-and-forget pub/sub (`nats bench`). No disk, no replica ack.
+- **JetStream** uses **file** storage and **replicas=3** (same as product streams). The unique stream `benchstream` is deleted between JS loads.
+- Throughput is **msgs/sec** from nats CLI **0.1.6** (`--no-progress --csv`). Its min/avg/max are publisher **rate spread**, not delay.
+- **Ping** delay: one publisher, sequential publish-then-wait. This is one-message round-trip through the cluster.
+- **Flood** delay: N publishers dump the whole batch, then the subscriber drains. This is **queueing under burst**, not wire RTT.
+- Probe: `scripts/latency.mjs` (two connections, header timestamp).

+## What the numbers mean
+
+Product job/event/archive traffic is **JetStream r=3 file**. On this three-LXC stand that is about **16k durable 128 B pubs/s** (about **13k** at 1 KiB). Core NATS is an upper bound for non-durable fan-out: about **0.7–2.0M msgs/s** aggregate at 128 B, or **~630k msgs/s (~616 MB/s)** at 1 KiB with 4 publishers.
+
+A quiet request-reply is **~0.3 ms** average, **p99 < 1 ms**. Flood rows in the **150–500 ms** band are the subscriber catching up after a burst, which is what a job-events mailbox sees if publishers outrun consumers.
+
+Re-run on NS1: `bash scripts/bench.sh`. Raw logs/CSVs are under `results/<utc>/`.
