If someone had time, it might be interesting to profile something that feels slow in an --enable-debug --enable-optimize build and see if anything stands out. These builds will always be a little slower than the builds we ship (because they're not PGOed), but it would be nice if they were at least usable. Making them faster would also make our debug test runs in automation faster, which is a nice win! (We spend *a lot* of CPU time running debug tests in automation.) -Ted _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
