I've already done this, and I post the results on this list. Check it out...
BTW it seems that profiling servers doesn't give coherent results: they give
different results just making apparently insignificant modification to the
code. Watching the code of glibc & gnumach, it seems that system call used
by gprof'ed executable take in account only a thread so results can be not
completly significative. A mono thread (or bi-thread) server can help in
profile it, it would better than nothing.
PS: I've also already post some results and comparison of hurd vs linux
using bonnie++.
