Usually the operating system does this for you, by caching some of the physical disks in RAM. For a forward proxy like you have setting a large cache_mem isnt recommended IIRC. > i've got 6 GB of ram, so i dont mind doing so.. any advice? > would it do good or .. ? The more ram the better. The OS should use it as disk cache as I mentioned above. Are you using a 64bit OS (better) or a 32 bit OS with PAE? If your OS reports a lot less that 6 gig you'll want to fix that. You might find running a cache only DNS server helps, as it should cut the lookup latency across the saturated link (tho it probably wont save much in the way for throughput).
