Thanks for your prompt reply. Well I am not much experienced admin in linux or in terms of squid, and therefore I havent installed wireshark/tshark/tcpdump in squid yet, but I will install it now to go in deep. My previous version of squid was 2.7 Stable downloaded from aptitude which was installed in a different machine, and not in this new machine. My current configuration in the current PC (Core i7) is a squid 3.1.10 custom compiled by me with only the ZPH and the Linux Net Filter enabled. I haven't used any other parameters while configuring it. Default Cache_Dir is splitted into three directories: UFS /media/cache/storage501 51400 16 256 UFS /media/cache/storage502 51400 16 256 UFS /media/cache/storage503 51400 16 256 and cache_mem is 150MB Sometimes during peak hours while the network load is high, we do experience very slow browsing (in all websites) which is usually resolved after a quick restart of the squid process/service.
