I am using simple file extension based delay pools. This is what the config looks like: acl big-files url_regex -i .flv .avi .wmv .mpg .mpeg .mpe .divx .mov .qt .mp3 .wav .ram .rm .rar .zip .gz .bz2 .iso .exe .rpm .deb .raw delay_pools 2 delay_class 1 3 delay_access 1 Allow big-files lan delay_access 1 Deny all delay_parameters 1 524288/524288 -1/-1 16384/4194304 delay_class 2 1 delay_access 2 Allow lan delay_access 2 Deny big-files delay_access 2 Deny all delay_parameters 2 -1/-1 The "downloads" delay pool is rarely, if ever, less than 90% utilized, according to squidclient (the "current" reading). That would mean ~4 Mbps + normal browsing bandwidth. But the server in traffic, at the same time, is ~120 kBps. Shouldn't it be much higher?
