Summary

Reconciles the PHP performance retrospective with the work that is actually merged into develop and adds a concise Performance section to CHANGELOG.md.

This documentation-only PR is based directly on develop@d707064245c90e686968cbfb9d38cfe5097fd760 with one commit and no merge commits.

Landed work documented

Candidate status

The changelog includes the intended #1316/#1317 release benefits. The retrospective labels them pending so those entries can be removed if either candidate does not pass live-stack validation.

Validation

  • git diff --check: passed.
  • Retrospective markdown lint: passed.
  • Branch divergence: exactly one commit ahead of current develop, with no merge commits.
  • Only CHANGELOG.md and docs/php-performance-optimization-retrospective.md changed.
  • Stale aggregate memory, TTFB, SQL, and HTTP totals were removed because the exact final candidate set has not been remeasured.

This PR must remain unmerged until final live-stack validation and candidate selection are complete.

Estimated code review effort: 2 (Simple) | ~10 minutes

Mergeability Score: 🔵 Low · up to be8e0

The PR does not change production behavior, but it should merge with owner awareness that several retrospective statements need correction or clarification so the documented benchmarks and implementation history remain accurate.

match the analytics-specific measurements of 37–42.8%; do not include the 54.8%
failing-remote-read result in that analytics range, or report it separately with
its remote notice and translation-check context.
- Line 111: Update the subscriber privacy lookup entry in the performance
retrospective so the speedup matches the displayed timings: use approximately
1,130× faster, or explicitly document that approximately 1,159× is calculated
from unrounded median timings and include those timings.
