Hi , we have been using squid 3.1.20 comes with debian wheezy 7. We could see there is a peformance hit in http traffic when we use Squid.
For each HTTP GET request coming from client to proxy server, Squid takes nearly 2 seconds to generate HTTP GET in order to establish a connection with server. There is always a ~2 second delay between the request coming to our system and going out of Squid. Suppose if a page has lot of embedded URL's it's taking more time with squid in place.Suppose If I disable squid the page loads very fast in client browser. What could be the reason? Do I need to tweak any configuration for this? The first page request always loads slow with Squid. *Configuration*http_port 3128 http_port 3129 tproxy http_port 80 accel defaultsite=example.com acl manager proto cache_object acl localhost src 127.0.0.1/32 ::1 acl to_localhost dst 127.0.0.0/8 0.0.0.0/32 ::1 acl QUERY urlpath_regex cgi-bin \? cache deny QUERY acl denied_status_404 http_status 404 deny_info http://example.com/ denied_status_404 http_reply_access deny denied_status_404 acl denied_status_503 http_status 503 deny_info http://example.com denied_status_503 http_reply_access deny denied_status_503 acl SSL_ports port 443 acl Safe_ports port 80 acl Safe_ports port 21 acl Safe_ports port 443 acl Safe_ports port 70 acl Safe_ports port 210 acl Safe_ports port 1025-65535 acl Safe_ports port 280 acl Safe_ports port 488 acl Safe_ports port 591 acl Safe_ports port 777 acl CONNECT method CONNECT acl PURGE method PURGE http_access allow PURGE localhost http_access deny PURGE http_access allow manager localhost http_access deny manager http_access deny !Safe_ports http_access deny CONNECT all http_access allow all icp_access allow all tcp_outgoing_address x.y.z.5 acl VIDEO url_regex ^http://example\.examplevideo\.com cache allow VIDEO cache_mem 100 mb maximum_object_size_in_memory 10 kb memory_replacement_policy heap LFUDA cache_replacement_policy heap LFUDA cache_dir aufs //var/logs/cache 6144 16 256 store_dir_select_algorithm round-robin maximum_object_size 51200 kb cache_swap_low 70 cache_swap_high 80 access_log //var/logs/access.log squid cache_store_log none logfile_rotate 1 mime_table //var/opt/abs/config/acpu/mime.conf pid_filename /var/run/squid3.pid strip_query_terms off cache_log //var/logs/cache.log coredump_dir //var/cache acl apache rep_header server ^apache refresh_pattern -i ^http://.wsj./.* 10 200% 10 override-expire override-lastmod reload-into-ims ignore-reload refresh_pattern -i \.(gif|png|jpg|jpeg|ico)$ 480 100% 480 override-expire override-lastmod reload-into-ims refresh_pattern -i \.(htm|html|js|css)$ 480 100% 480 override-expire override-lastmod reload-into-ims refresh_pattern ^ftp: 1440 20% 10080 refresh_pattern ^gopher: 1440 0% 1440 refresh_pattern -i (/cgi-bin/|\?) 0 0% 0 refresh_pattern . 0 20% 4320 quick_abort_min 0 kb quick_abort_max 0 kb negative_ttl 1 minutes positive_dns_ttl 1800 seconds store_objects_per_bucket 100 forward_timeout 2 minutes shutdown_lifetime 2 seconds visible_hostname x.y.z.3 server_persistent_connections off dns_nameservers x.y.z.1 x.y.z.2 ipcache_size 8192 fqdncache_size 8192 memory_pools off Regards, Saravanan N
