I would be interested in having this subject clarified again. I'm playing with 3.1.15 and I have not configured cache_dir. Hence, all my hits can only be from memory. Look at those numbers for example (very idle system, I agree): You can see no storage but still 99.6% of the hits are marked Disk hits and 0.4% are marked as Memory hits. Can someone please help me understand the numbers here? -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/TCP-HIT-and-TCP-MEM-HIT-tp1026865p4549174.html Sent from the Squid - Users mailing list archive at Nabble.com.
