Dear All, Relevant info: On IBM Server 3650 x series with physical RAID 1 . Disk space comprises of 70 Gb Intended is caching of windows update. intended is caching of youtube contents. Single is dedicated to running squid on Ubuntu 8.04 Current Settings : cache_dir aufs /usr/local/squid/var/cache 50000 16 256 However i beleived that it should be changed to something like this: cache_dir aufs /usr/local/squid/var/cache 50gb 48 768 or cache_dir aufs /usr/local/squid/var/cache 20000 32 512..... etc etc. so that not more file lies in L2. The confusion is that isnt it correct to allocating this large 50gb hard-disk space to caching? Does such large cache will result in some issues? Does this large size has to do with some latency issue etc? I am looking forward for your guidance. regards@all _________________________________________________________________ Hotmail: Free, trusted and rich email service. https://signup.live.com/signup.aspx?id=60969
