Performance Chat Summary: 17 June 2025

The full chat log is available beginning here on Slack.

Open Floor

• @swissspidy shared a previous question from @spacedmonkey, regarding the use of static variables in core for in-memory caching, and whether the object caching API with a non-persistent cache group might be a better alternative. Benefits noted included cache invalidation capabilities and improved testing scenarios.
  In the original discussion thread:
  • @flixos90 questioned the practical advantages of cache invalidation for non-persistent caches.
  • @spacedmonkey clarified it would allow developers to optionally enable persistent caching, improve testability by clearing caches between tests, and align with the intended usage of the object cache API.
  • @flixos90 agreed that while making these caches persistent could introduce issues, improved testing practices were indeed a valid benefit.
• @spacedmonkey also requested feedback on PR #8728, inviting further input from contributors.
