I’m always looking for ways to speed up my Mozilla build, since it allows me to test my changes even quicker. I was really excited when I found out about make -s tier_app, since it sped up my compiles by a huge amount.
make real 10m22.630s user 4m28.072s sys 1m27.807s
make -s tier_app real 0m14.426s user 0m6.502s sys 0m3.957s
But yesterday, on IRC, I heard about libs_tier_app, which is ever faster, if you haven’t changed any IDL files (which I usually don’t).
make -s libs_tier_app real 0m9.407s user 0m5.440s sys 0m3.065s
Okay, it’s not nearly as good as going from 10 and a half minutes to 15 seconds, but a 30% (or is it 50%) speedup is still nothing to sneer at.
