This is a confirmed 0.4% progression on Speedometer according to A/B bots. 1855088 1 455760 cdumez 2022-03-25 07:44:10 -0700 Created attachment 455760 Patch 1855136 2 455760 ggaren 2022-03-25 09:54:09 -0700 Comment on attachment 455760 Patch r=me 1855160 3 ews-feeder 2022-03-25 10:40:17 -0700 Committed r291866 (248872@main): <https://commits.webkit.org/248872@main> All reviewed patches have been landed.
