should install and use http://wiki.squid-cache.org/Features/CacheManager This gives you a lot of info regarding cache performance, like hit rate etc. Having 556 GB of cache within one cache dir might already hit the upper limit of max. number of cached objects, depending upon the avg size of objects in cache. Which could mean, that only part of the 556GB will ever be used. Solution: Create different cache dirs, for various object-size classes. But before doing this, post the infos you get from CacheManager, like avg object size, cache fill rate etc. CacheClient is the alternative to CacheManager, in case you do not want to use web access. -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/Squid-monitoring-access-report-shows-upto-5-to-7-cache-usage-tp4661301p4661314.html Sent from the Squid - Users mailing list archive at Nabble.com.
