OK, I thought of the cache_dir while I was writing, but in general, the cache_mem is the configuration we can change from, let's say, 8 GB to 32 GB in a minute. What i was asking was: if i have 40 GB of RAM, can I set something like 32 GB to cache_mem, making the box operate with about 39GB of memory effectively used, and leaving only something like 1 GB, or less, for that linux "cache" thing? In a box without a proxy-cache, let's say, a DNS server, linux will not use nothing more than 1GB of RAM, doing no "disk cache". But the fact is that you can put 100GB on a linux box with squid, with only 2 GB of cache_mem, 20 GB of cache_dir, and we will have about 4GB of RAM effectively used, and all the rest of the memory will be "used" as disk cache by linux. There's no real need for that? Can we grow the effective usage, configuring squid, until we have no memory used for "cache" by linux?
I suspect so. The kernel should be auto-adjusting its cache usage. Amos
