Bugger all difference in total. The problem is more likely to be WCCP, most of the installs I hear about with TPROXY/WCCP are broken somehow. Not to say there aren't some working, but I've heard less cries for help ending in success. As for overall scaling. Less than 10K requests though for those on regular proxy duty. We've seen 50Mbps pipes being flooded by Squid-3 no problems. Above that you need to start tuning stuff like disks, reducing ACLs, multiple Squid etc to fill the pipe. Amos
