[isp-caching] Re: unusually high cpu load with squid

[Timur Irmatov <thor@...>]

I'm running squid pool on ext3 filesystem, but this does not seem to
be the cause of the problem.  I tried ext2 with same result.  I have
even tried to install FreeBSD 4.9 on this machine.  No luck.  Squid
consumes a lot of cpu on both systems - Linux & BSD.
