Hey thanks for the input This web cache proxy server is a dedicated machine running ubuntu 64bit OS (no gui) with 5gigs of RAM and a 1TB drive dedicated to the cache. Only using 500GB currently. (The OS is on a different 80GB drive) Accordign to the math of 10MB of RAM per 1GB of Disk space that would put me right at 5GB of RAM. Yesterday I increased the maximum_object_size value to 32MB from the default of 4MB and haven't noticed any difference in the cache size. I think I'll push it up around 50MB. I tried to change my L1 and L2 values from the default "16 256" but it didn't like the change because the squid service didn't restart until I changed it back. I don't think I tried "256 256", so I'll try that next. I will need to read up on and expirement with refresh_pattern -- View this message in context: http://www.nabble.com/not-caching-enough-tp25530445p25578014.html Sent from the Squid - Users mailing list archive at Nabble.com.
