  • Performance work: 

    • [acreskey] Will be meeting w/ Emma from privacy on design of Bounce Tracking Protection experiment - let me know if you’re interested

    • [jesup] RaceCacheWithNetwork does in fact slow down loads in CI

      • Up to 20% speedindex, 25% FCP, 40% LCP

      • Likely mostly for SSDs

      • CI should be close to best-case SSD - 0 delay, infinite bandwidth

      • RCWN win stats bad - most network wins (on SSD) are actually expired cached data to be replaced with data from network, etc.

      • Will do experiments

      • Previous rcwn experiment: https://experimenter.services.mozilla.com/nimbus/impact-of-race-cache-with-network-feature/summary
