Talospace ☛ The Talospace Project: Updated Baseline JIT OpenPOWER patches for Firefox 128ESR
I updated the Baseline JIT patches to apply against Firefox 128ESR, though if you use the Mercurial rebase extension (and you should), it will rebase automatically and only one file had to be merged — which it did for me also. Nevertheless, everything is up to date against tip again, and this patchset works fine for both Firefox and Thunderbird. I kept the fix for bug 1912623 because I think Mozilla's fix in bug 1909204 is wrong (or at least suboptimal) and this is faster on systems without working Wasm. Speaking of, I need to get back into porting rr to ppc64le so I can solve those startup crashes.

Mozilla ☛ Mozilla Performance Blog: Performance Testing Newsletter (Q3 Edition)
Welcome to the latest edition of the Performance Testing Newsletter! The PerfTools team empowers engineers with tools to continuously improve the performance of Mozilla products.
Last quarter was MozWeek, and we had a great time meeting a number of you in our PerfTest Regression Workshop – thank you all for joining us, and making it a huge success! If you didn’t get a chance to make it, you can find the slides here, and most of the information from the workshop (including some additional bits) can be found in this documentation page. We will be running this workshop again next MozWeek, along with a more advanced version.
