Squid does lots of fork() calls doesn't it? fork() is pretty expensive
on solaris, the whole platform is geared towards threads and
light-weight-processes.

That's probably it, I remember seeing graphs _ages_ ago showing this and
hilighting how amazingly good solaris threads are and how slow fork() is
in comparison.
