I'm try install squid to SMP machine, I've ran two copy of squid, and balance load between them. But I haven't seen any difference if I run one or two copy of squid, first
processor has higher load then second. Is it normal? How can I see what cpu number squid used?
1) This is output of sar when two copy of squid (with diskd) is running.

2) One squid (with diskd) ( high %iowait because it has full 80GB cache)
