Building LLVM (even a release build with asserts disabled and with all of the cross-compile targets disabled) is an overnight job.

A lot of the more interesting platforms these days are significantly slower. And I doubt you do a build with a stock /etc/src.conf on such hardware either. The defaults for src.conf should be for the common case, and in the common case profiled library builds are in the noise. I do add WITHOUT_PROFILE to many of my machines in /etc/src.conf, but I still think they should be enabled by default. -- John Baldwin
