Hello to list, I am using squid 3.0.STABLE7. Can i use squid for caching server in a ISP like environment. If yes, then what should be the H/W configuration? I have gone through to various articles found in google. In my observations since Squid is a single threaded(not a multithread) s/w, so there is no need to use dual/quad core processor, and RAM is also not very important factor because somewhere i read, "10MB RAM for every 1 GB of cache space on disk". So RAM is also ok. I will use 4-8 GB RAM and it should be fine. I think i am going/thinking into right direction. Please suggest me, what should be the H/W requirement for the server where you can expect 1200-1500 concurrent connection to the squid at a time.
