The profile section in docs/contributing/benchmarks.md says how to run
scripts/bench/boot-profile.ts, what the profile of the v1.44 runtime
found (the worker graph as one 753 ms block, a live heap of about
165 MB of which the query compiler holds 50 and the catalogs 33) and what
changed. scripts/bench/results/v1.45.0-*.md hold the before and after
numbers per area, from back-to-back runs on the same machine. The size
baselines take the lowered numbers.
Seven matchers built their index over every shipped catalog at module
load (the GLP-1 tag map, the nutrient and metric names of the MCP reads,
the SNOMED and LOINC lab names, the Coach's health words, the lab-name
pattern), so loading the worker graph read all eight catalogs at boot.
Each index is now built the first time it is asked for.
The boot profile records the change: the longest busy stretch of the
main thread at boot fell from 753 ms to 241 ms, the live heap after five
idle minutes from 164 to 152 MB, and the catalog chunk sources (two of
9.7 MB) are gone.
scripts/bench/boot-profile.ts starts the production build with every role
under the production heap ceiling against the seeded benchmark database,
and records the time to a healthy probe and to a ready worker, every
event-loop stall the process logs, the heap lines, the full collections
from --trace-gc, the main thread's busy stretches during the boot with
their self time by source module (resolved through the chunk source maps),
and one heap snapshot after an idle wait, summarised by node type,
constructor, largest strings and largest retained subtrees.
The baseline on the current runtime: a 753 ms busy stretch at 0.7 s, most
of it the worker graph, and a live heap of 164 to 172 MB after five idle
minutes, of which the query compiler holds about 50 MB and the eight
locale catalogs about 33 MB (32 parsed copies and two 9.7 MB chunk
sources).
One run of scripts/bench/run.ts against the seeded account (1,266,549
measurement rows, anchor 2026-10-22), 20 measured requests per row after 3
warm-up requests, web-only production build, 792 MB heap ceiling, Postgres
16.15. The commit adds only lint rules, guards, tests and scripts on top of
v1.44.0, so the server code measured is the v1.44.0 code.
Cold (caches evicted before each request), p95 and statements per request:
/api/auth/me 17 ms / 19, dashboard summary 233 ms / 31, dashboard snapshot
2253 ms / 158, pulse series 30 d 59 ms / 8, 365 d 311 ms / 8, 3650 d
2118 ms / 8, day view 78 ms / 49, insights health status 140 ms / 68,
correlations 105 ms / 45. Warm, the snapshot is 24 ms / 13 and the 3650-day
series still 1506 ms, since that read is not cached. The 5,000-row batch
ingest took 1722 ms and 424 statements over ten requests.
The machine was shared with other work during the run (load average 8 to
20), so latency is indicative; the statement counts do not depend on it.
The results directory is written by the script and left out of prettier,
so a re-run diffs cleanly.
