Squid 2.4STABLE2 is great with AUFS. Kernel 2.4 is not. Some have had
good luck with it, and I find it quite nice for SMP machines...however,
it still has some big ugly bugs that make it not so nice. I've said it
a few times before on this list, but people come and go so I'll say it
again: kernel 2.2.16+ is faster than any kernel 2.4 revision I have
tested for Squid workloads on a single CPU machine. For SMP machines
kernel 2.4 provides better balancing across processors, and finer
grained locking for other system tasks.

If your hardware is well supported by 2.2.19, use it. If you have SMP,
or hardware that works better with 2.4, then I wish you good luck.

Someday soon, (like once I get a stable kernel 2.4 RPM built) I plan to
update the article to reflect the new Squid possibilities for
performance. Probably covering DiskD for the FreeBSD crowd. COSS may
get a mention if it is getting closer to stability by then (that will
depend on how long it takes me to get around to the update--I think
Adrian still has big plans for the COSS code, and it will continue to
see major breakage along the way--but it's very cool and very exciting
stuff).
