Hello all, over at freesound ( http://freesound.iua.upf.edu ) we're slowly but surely going over 3TB/month and we thought we would use squid for "mirroring" the content. Freesound hosts a lot of rather large (2MB->600MB) audio files. The whole Freesound colection of files is about 260G large. We set up 2 test-servers elsewhere with this config file : http://pastebin.com/f3f34e0c2 (search for FREESOUND_TODO to see the changed values ). What we have noticed is that the upload/download ratio of these test-machines is very close to 1 and isn't really lowering. In the log files we see a lot of TCP_HIT, SWAP_OUT and RELEASE. One of the test servers was running with 70GB of cache (of which only 27GB used!). When the cache was augmented to 90GB this morning (for testing), the ratio suddenly jumped to something MUCH better. We're a bit confused, and it would be nice if someone could have a look at our config files to see if we have missed something obvious... kindest, - bram -- http://freesound.iua.upf.edu http://www.smartelectronix.com http://www.musicdsp.org
