Thats 2400 requests a second at a decent hit rate on hardware from 2000. They optimised the crap out of the data path to avoid multiple copies of data both in user and kernel space; I'm sure their userspace code was also pretty lean. Now, before you go "21x18 gig disks, 2400 req/sec, understandable" realise that means they're capable of doing ~ 1200 req/sec per single CPU. PIII-Xeon-733's. Squid doesn't get that far on a PIII Xeon 733 - I can't get it past 200 req/sec at the moment on my Xeon 600MHz, even with Squid-2.HEAD. Any guesses what thats capable of on modern hardware? :) Adrian -- - Xenion - http://www.xenion.com.au/ - VPS Hosting - Commercial Squid Support - - $25/pm entry-level bandwidth-capped VPSes available in WA -
