[squid-users] Peak Load on single instance of squid running on Dual Xeon 2.2GHz

Hi,

I am managing a busy cache with 1000 active users. There server is Dual Xeon
2.2 GHz / 2304MB RAM and 6x36GB 10K RPM. Currently, I am using 2 disks for
cache.

I am using 2.5.STABLE3 with aufs/reiserfs.

The CPU utilization is peaking at 95% and above when the box does about 150+
req/sec.

Can this box handle more traffic ?
