I recently bisected my mozconfig after I realized that my builds were appreciably slower than I expected; I discovered that the main reason for this is the clang-plugin, which caused approximately a 50% slowdown in my local build time: ``` ## No Clang Plugin $ ./mach clobber && time ./mach build real 9m9.583s user 201m22.020s sys 11m16.940s ## Yes Clang Plugin $ ./mach clobber && time ./mach build real 15m21.131s user 366m14.555s sys 13m44.436s ``` This has eaten a large amount of my build time over the past while; it would be nice if running the clang plugin didn't cause builds to slow down by 50%.
