S.O Version: Red Hat Enterprise Linux AS release 3 (Taroon Update 4)
CPU: Intel(R) Xeon(TM) CPU 3.20GHz (SMP)
RAM Memory: 2G.

With 3 cache disks:
/dev/sdb1 69G 46G 24G 66% /usr/local/etc3/cache1
/dev/sdc1 69G 46G 24G 66% /usr/local/etc3/cache2
/dev/sdd1 69G 46G 24G 66% /usr/local/etc3/cache3

[root@proxy bin]# grep cache_dir ../etc/squid.conf
cache_dir aufs /usr/local/etc3/cache1 60000 16 256
cache_dir aufs /usr/local/etc3/cache2 60000 16 256
cache_dir aufs /usr/local/etc3/cache3 60000 16 256

Do you need more specs?

Thanks
