With defender disabled the best I can get is 18min. This is on one of the new lenovo p710 machines with 16 xeon cores. I definitely observed periods where it was not CPU bound. For example, at the end of the js lib build I observed a single cl.exe process sit for ~2 minutes while no other work was being done. I also saw link.exe take a long time without parallelism, but i think that's a known issue. _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
