I found that squid is consuming too much cpu, average cpu idle time is 49 only. I have attached the output 'top -b -n 7', and 'vmstat 1' below is the output of squid.conf squid.conf: --------- http_port 8080 cache_mgr administra...@test.com cache_mem 1024 MB cache_dir aufs /var/cache/squid 20000 32 256 visible_hostname gateway.test.com refresh_pattern ^ftp: 1440 20% 10080 refresh_pattern ^gopher: 1440 0% 1440 refresh_pattern -i \.(gif|png|jpg|jpeg|ico)$ 10080 90% 43200 refresh_pattern -i \.(iso|avi|wav|mp3|mp4|mpeg|swf|flv|x-flv)$ 43200 90% 432000 refresh_pattern -i \.(deb|rpm|exe|zip|tar|tgz|ram|rar|bin|ppt|doc|tiff)$ 10080 90% 43200 refresh_pattern -i \.index.(html|htm)$ 0 40% 10080 refresh_pattern -i \.(html|htm|css|js)$ 1440 40% 40320 refresh_pattern . 0 40% 40320 cache_swap_low 78 cache_swap_high 90 maximum_object_size_in_memory 100 KB maximum_object_size 12288 KB fqdncache_size 2048 ipcache_size 2048 acl myFTP port 20 21 acl ftp_ipes src "/etc/squid/ftp_ipes.txt" http_access allow ftp_ipes myFTP http_access deny myFTP acl porn_deny url_regex "/etc/squid/domains.deny" http_access deny porn_deny acl vip src "/etc/squid/vip_ipes.txt" http_access allow vip acl entweb url_regex "/etc/squid/entwebsites.txt" http_access deny entweb acl mynet src "/etc/squid/allowed_ipes.txt" http_access allow mynet please help, why squid is utilizing so much of cpu -- Regards Muhammad Sharfuddin | NDS Technologies Pvt Ltd | +92-333-2144823
