Thats not strictly true with 'good' IDE chipsets these days. You should see how Squid benchmarks with COSS on an Intel ICH7 SATA motherboard. Holy smokes.. Ok, lets see. V65x. routing 40-ish megabits of traffic with 20ish megabits of Squid? It shouldn't be that bad, not by a long shot. You've got a good CPU, decently fast FSB. Which chipset does that box use? Can you paste an "lspci -v" output here? That high IOWAIT time does suggest your Squid is doing a little too much synchronous IO. Try disabling the access and cache logs: cache_access_log none cache_store_log none Adrian
