>In the 64 bit environment, squid process (64 bit binary) ideally should consume more memory when it is configured with large disks ( 10MB for 1 GB) I have 1TB configured for my cache_dir. I would assume that squid would consume 10GB memory at lest. However it stays at 3.8GB consumption.< Depends on. I have multiple squid-instances running within 16GB, also in sandwiched config, 2 of them manage the 2 cache_dirs, on 2 disks, 1.8TB each. Memory footprint is 2.1GB for each squid, managing 1.8TB each. BUT: I only cache large objects. The point is, that memory consumption mainly depends upon number of objects cached. AFAIK, 2**24 objects max. in one cache_dir, about 80bytes (may be something more for 64 bits) for every object. You should check the avg size of the cached objects in one cache_dir, first. And then use maths from above for a rough estimate. -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/squid-2-7stable-64bit-will-not-use-available-memory-tp4661541p4661546.html Sent from the Squid - Users mailing list archive at Nabble.com.
