Replaces unbounded `Promise.all(relays.map(...))` calls with `pMap` using a concurrency limit of 3 for background operations like history hydration, metadata fetching, and DM sending. This prevents network saturation and potential main-thread jank when many relays are configured. Includes benchmark verification script `benchmarks/relay_concurrency_repro.mjs`. Audited upload docs and confirmed accuracy. Co-authored-by: PR0M3TH3AN <[email protected]>

# Daily Performance Report - 2026-02-08
|
|
|
|
**Summary:** Bounded background relay concurrency to 3 to prevent network saturation and UI freezes. Verified upload documentation accuracy.
|
|
|
|
## Findings
|
|
|
|
### P1: Unbounded Relay Concurrency
|
|
- **Location:** `js/nostr/client.js` (`fetchAndCacheNip71Metadata`, `hydrateVideoHistory`, `_sendNip17DirectMessage`).
|
|
- **Impact:** Simultaneously opening connections to all relays (could be 20+) caused network congestion and potential UI jank.
|
|
- **Fix:** Implemented `pMap` with `RELAY_BACKGROUND_CONCURRENCY = 3`.
|
|
- **Status:** Fixed.
|
|
|
|
## Metrics
|
|
- **Max Concurrent Relay Requests:** Reduced from N (number of relays) to 3.
|
|
- **Login Time:** (Not measured directly today, but expected improvement due to reduced initial load).
|
|
|
|
## Docs Audit
|
|
- **Page:** `content/docs/guides/upload-content.md`
|
|
- **Result:** Verified accurate. Matches code behavior for file types, size recommendations, and HTTPS enforcement.
|
|
|
|
## Artifacts
|
|
- [PR #1] perf: bound relay background concurrency
|
|
- `benchmarks/relay_concurrency_repro.mjs` created.
