# Runtime Health Performance Profile

Generated: 2026-05-21T13:57:34.596Z
Source: `node ai/runtime/dist/cli.js performance runtime-health-profile --json`

## Summary

- Runtime Health performance is measured before optimization.
- Admin Runtime Health source does not reference Prisma/DB access, so a GraphQL DB N+1 is not indicated by this path.
- Socket.IO remains invalidation-only; performance work must not move dashboard truth into socket payloads.
- Measured bottleneck category: Runtime Health snapshot generation/projection (595.5 ms median, 24401 gzip bytes median).
- Slowest measured projection phases: governance validator 5058.4 ms; scheduler snapshot 2079.6 ms; runtime services 835.2 ms; leases 828.1 ms; wait graph 778.5 ms; dispatcher summary 771.2 ms; lock graph 549.7 ms; operations 372.4 ms.

## DataLoader Decision

Do not add DataLoader: The measured Runtime Health path is dominated by Runtime snapshot generation and backend proxying, not repeated GraphQL database resolver access.

DataLoader/request batching remains deferred because this path is not a repeated nested GraphQL DB resolver path. The next optimization target should be Runtime snapshot generation, snapshot splitting, or sparse Runtime Health queries if operator-visible latency remains too high.

## GraphQL N+1

Admin Runtime Health resolver delegates to service methods and the measured service path does not use Prisma/DB queries.
