We don't use any disk for cache, just "cache_dir null /tmp", the
following option controls how much memory squid uses:

memory_pools off
memory_pools_limit 1 MB
cache_mem 6500 MB
maximum_object_size_in_memory 4096 KB
memory_replacement_policy heap LFUDA

In this case, CPU is not bottleneck generally, I THINK dual-channel
memory and FSB speed is much more important.
NIC(network card) could be bottleneck too, at least we encountered,
too many interrupt from NIC limited the traffic no more than 550Mbps.
I have not touch that line in production enviroment, but it is
possible.

BTW, may bonding of multiple NICs helps on too many interrupts.
