Notice that for the majority of the packages, it doesn't matter if it
has been compiled optimized or not, only glibc, gcc (if you are a
developer), kernel and a few other packages are really important. It
is really the same if your xbiff/xclock whatever takes 0.01 ms or 0.1
ms, it is a 10x improvement (which I think that is very difficult to
achieve) and you will not we seeing the difference.
