But wall time was within measurement variance. -16s wall time / 2% isn't much on a 16-17 minute build (on this 2 year old machine). It will be longer on Windows (because Windows) and on machines with fewer cores (hopefully you are building with 4+ cores). But it is still a net reduction. C++ building already scales up to several cores and uses ~100% CPU. So the only way to make C++ build faster is by not building so much or building what we have more efficiently (avoiding complex templates, etc). _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
