I don't know how you got these results but what I observed under Linux is
about 60% of CPU time spent in kernel code (and almost nothing is user land).
The problem with the Hurd is that we cannot see how much time is being spent
in kernel space. We can expect that some time is spent in the kernel code (ie.
device driver for instance) beside the 30% of the ext2 server itself.
Is there a way we could check that? Does libps handle kernel CPU time
information?
Thanks,
Ludovic.
