May I offer a small suggestion?

With glibc 2.1 and 2.2 kernels, poll() is fully supported and doesn't
suffer from the 1024 filedescriptor limit that select does due to
__FD_SETSIZE.

So what I do is

- Use glibc 2.1
- Use 2.2.13 or up
- configure squid with ./configure --enable-poll
- after configure has run, I edit include/autoconf.h and change
  SQUID_MAXFD to 3000 (or whatever you like, squid will scale it
  down at runtime to the process' maximum anyway).

You still need to set the ulimit ofcourse. You can do this as root
as you say, or use the small setuid patch.

But to increase the global ulimit you do NOT need to recompile
the kernel. You can do it in /etc/initscript - read the
manpage of initscript(5) for more info.

Mike.
