I can only tell about a multi-2.7 config, running one 2.7-squid for authentication and load distribution, and 2 more 2.7-squids as backends on a 4-core machine. Using 2.7 because of some unique features and private patches. And, because I consider it "rock-solid" for my requirements. This config works similar to SMP in newer squids, taking advantage of multiple cores. -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/squid-squid3-running-at-the-same-time-can-we-get-benefit-tp4662785p4662788.html Sent from the Squid - Users mailing list archive at Nabble.com.
