Re: Build times of hurd and glibc for different versions of gnumach, hurd and glibc

[Samuel Thibault]

Hello,

Thanks for the investigation.  I have added the attached patch to the
gnumach running on the buildds. That'll revert to the old page cache
policy, which seems to be reverting to the previous performance.

Looking at ps -feMj, it seems that it's ext2fs which consumes much more
CPU time, thus increasing overall wallclock time. It'd probably be
interesting to profile ext2fs, to see what takes longer. Perhaps it's
the hash table which is less efficient since with the new page cache
policy there are much more cached files?
