Hi, We are moving to new more powerful servers with CentOS 6 64bit instead of CentOS 5, with SSD instead of HDD and with Squid 3.3.9 instead of Squid 2.6.STABLE21. We are running Squid as a reverse proxy. The performance of Squid 3.3.9 seems to be excellent tested with around 125087 "clients accessing cache" and 20000 "file descriptors in use" in a single server but there is one big problem: we are getting much worst percentage of hits in Squid 2.6 in comparison with the same config in Squid 2.6. With the same config we are getting around 99% of hits in Squid 2.6 and just 55-60% of hits on Squid 3.3.9 We are using the refresh_pattern options override-expire ignore-reload (as mentioned before is the same squid.conf config in every server -old and new ones-) Any idea on what might be the problem or any suggestion on how to find it? Thank you in advance PS: Since we have lots of concurrent connections requesting the same addresses we expect to add to the main webpages the Cache-Control stale-while-revalidate=60 header which I guess that will increase the number of hits on the servers running Squid 3.3.9 but for the moment the goal is to first try to reach a more similar percentage to Squid 2.6 in the same situation since stale-while-revalidate would be ignored by Squid 2.6. -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/Why-are-we-getting-bad-percentage-of-hits-in-Squid3-3-compared-with-Squid2-6-tp4662949.html Sent from the Squid - Users mailing list archive at Nabble.com.
