Re: Larger Compilations / Speed

[Andrew Pinski <pinskia at physics dot uc dot edu>]

The OS should cache the files for execution (on Darwin it does)
so it looks more like an OS problem rather than a gcc problem.
Yes a compile server will help but still an OS problem exists
and can hurt other programs.

Thanks,
