Hello,

I have installed latest stable version of squid (2.5 stable 12)
on a server with the following specs dual xeon 3.2 ghz, 1gb ram, 4x36.4 gb scsi 15k rpm (raid 4 i think)

When i start squid with the acl's i have defined in squid.conf cpu goes to 99% and memory to about 60% and browsing thru squid is painfull, like 60-80% decrease in browsing and loading of sites.

When i comment out the acls its working just fine (0.2-1.1% cpu and 0.1% mem) and browsing speed is just normal.

These are the acl's that give me the problems (or so i think, because if i comment those out its working just fine):
