Hi, How do I get Squid to use all my server memory as a cache and keep as many objects as possible in there? Squid is a great piece of software. I've been studying it's configuration for the last few days now and I'm really impressed with what I've seen. We have a fairly complex reverse proxy configuration building. I am now building the first ( of eventually many ) load-balanced Squid servers. Each Squid reverse proxy has 2GB of ram and *only* runs Squid. Absolutely nothing else will be on the server. The actually site being cached is under 1GB in size on disk. So conceptly Squid should be able to cache the entire site in memory and we should only see TCP_MEM_HIT in logs right? But right now, even under load the user is reporting Squid is using 13MB of memory and we're seeing a lot of TCP_HIT as opposed to TCP_MEM_HIT. How can we change this? My config looks like... # Feel free to use as much as needed cache_mem 1200 MB # Keep all the memory used memory_pools on # Don't let a few files hog memory. We don't have many large files anyway, but just in case maximum_object_size_in_memory 2048 KB # Replacement policy cache_replacement_policy heap LFUDA Thanks, Ralph
