Hi , I am facing some performance issues in squid . i.e. I have Debian etch with squid,squidguard,shorewall. Internet is working in normal speed if clients are approx 50 . If clients are approx 70 -100 it is getting very slow. I googled for tuning and done the following things, redirect_children 10 cache_dir ufs /var/spool/squid 1000 16 256 cache_mem 48 MB pipeline_prefetch on fqdncache_size 2048 maximum_object_size 8192 KB Can you please suggest me how can i improve much ? FYI : We have Leased line .so we are getting constant bandwidth. We are running the server in desktop HP Compaq with 4GB RAM, Core2Duo Thanks, MThanigairajan -- Thanks & Regards MThanigairajan The Most Certain Way To Succeed Is To Try One More Time -- By Edison
