Hello, I was used to getting efficiencies of around 50%. My current setup does not get past 10% as reported by Calamaris. There are around 40 people behind the proxy. After Googling around I added the following lines to squid.conf: cache_mem 256 MB maximum_object_size 32 MB maximum_object_size_in_memory 128 KB System has 512Mb of memory and very little other tasks. Is there anything else I can do to improve efficieny? Thank you, Bas ---- Bas Rijniersce IT Specialist @ Seaspan Ship Management E: brijniersce@xxxxxxxxxxxxx P: +1 604 638 2620 M: +1 604 616 4969
