Hello all, One more thing on the dynamic delay pool thing: I've tried the patch from the mail archive but it doesn't seem to be working ;( Not even with class 3 delay pools! You can find the threads about that patch in the mail archive at http://www.squid-cache.org/mail-archive/squid-users/200510/0280.html , and http://www.squid-cache.org/mail-archive/squid-users/200510/0320.html The build went just fine after patching those files (though I'm using Squid2.5Stable12). Then I made a simple test with two hosts, each mapped to a class 3 delay pool. Here are the relevant lines: #the alcs: acl pc_01 src 192.168.90.100/255.255.255.255 acl pc_02 src 192.168.90.101/255.255.255.255 http_access allow pc_01 http_access allow pc_02 http_access deny all #the delay pools: delay_pools 2 delay_class 1 3 delay_class 2 3 delay_parameters 1 64000/64000 64000/64000 64000/64000 delay_parameters 2 2000/2000 2000/2000 2000/2000 delay_access 1 allow pc_01 delay_access 1 deny all delay_access 2 allow pc_02 delay_access 2 deny all (The delay parameters for host, network, and aggregate buckets are equal for a pool since the test included only one host for each pool) Then I started 2 downloads from the same web server, one download in each client (pc_01, pc_02). The rates adjusted just fine, exactly as in the configs, but when I stopped the download on pc_01 (the faster download) the download rate on the other pc remained unchanged (approx. 2KB/s). Shouldn't it adapt and "borrow" some tokens from the unused buckets in the other pool? Isn't this the feature that dynamic delay pools provide? Could it be a problem that the two delay pools (class 3) are having clients from the same subnet? I imagine it shouldn't matter to Squid since each delay pool can (and should) manage its own clients independently. I've also made a test with class 1 delay pools and it behaved the same. If anyone has had any success with dynamic delay pools and the above mentioned patch in particular, or any experience at all, please let me know. Maybe I'm doing something wrong.. maybe I'm using the wrong patch for this version of Squid (Squid2.5Stable12), any help is most welcome! I'm looking forward to your replies All the best, Rudi -- -- http://www.fastmail.fm - And now for something completely different?
