Re: [squid-users] High load on squid machine after switching from reiserfs to ext3

Yep. Don't use ext3. ;-)

I've been able to crash kernel 2.4.9 (the Red Hat RPM kernels) at will
when running a Squid workload on ext3. I never looked very deeply into
it, because the performance of ext3 isn't comparable to ReiserFS. It
may be worth your time to grab the latest kernel SRPM, and rebuild it
with ReiserFS built into the kernel (rather than as a module).

I've had no problems with 2.4.9-31, on a quite large number of boxes.
