I'm hoping some squid experts can help me with this one .. I have a Karmic 64 bit server running at home acting as a home server. The server is acting as a default gateway with 2 NIC'S and is running squid. Four other computers are on the local LAN, which all are using the Squid as a proxy server. 3 Linux machines and one XP machine. When the browsers on all these computers are set to connect through the proxy server (I'm using wpad.dat for automatic proxy discovery on the lan) The browsers often hang, and the browsing experience can sometimes be horrible slow. Especially on the Linux machines running Firefox. And it keeps getting worse .. when the machine has been up for 7-14 days it seems like the Squid starts to timeout and drop connections, when that starts to happen the only way to fix the issue is to restart Squid. My server runs on rather good hardware so I suspect this is just a misconfiguration in my squid.conf The machine specs are the following .. Ubuntu Karmic 64 bit, headless server Intel Q6600 @ 2400Ghz, 8 GIG of RAM, and the OS disk is running on a 3Ware hardware raid controller using RAID1 via 2 500gb SATA2 discs. Total disc space on the machine is 8TB so the cache size could be increased I suppose. Here below is my squid config file .. please point out to me what could be better tuned in the config file. -------------------------------------- acl all src 0.0.0.0/0.0.0.0 acl internal_network src 10.0.10.0/24 acl vpn_network src 10.0.20.0/24 acl manager proto cache_object acl localhost src 127.0.0.1/255.255.255.255 acl to_localhost dst 127.0.0.0/8 acl SSL_ports port 443 563 # https, snews acl SSL_ports port 873 # rsync acl Safe_ports port 80 # http acl Safe_ports port 21 # ftp acl Safe_ports port 443 563 # https, snews acl Safe_ports port 70 # gopher acl Safe_ports port 210 # wais acl Safe_ports port 1025-65535 # unregistered ports acl Safe_ports port 280 # http-mgmt acl Safe_ports port 488 # gss-http acl Safe_ports port 591 # filemaker acl Safe_ports port 777 # multiling http acl Safe_ports port 631 # cups acl Safe_ports port 873 # rsync acl Safe_ports port 901 # SWAT acl purge method PURGE acl CONNECT method CONNECT http_access allow manager localhost http_access allow internal_network http_access allow vpn_network http_access deny manager http_access allow purge localhost http_access deny purge http_access deny !Safe_ports http_access deny CONNECT !SSL_ports http_access allow localhost http_access deny all http_reply_access allow all #Allow ICP queries from local networks only icp_access allow internal_network icp_access deny all visible_hostname proxy.mydomain.com cache_mgr me@xxxxxxxxxxxx forwarded_for off http_port 10.0.10.1:3128 transparent access_log /var/log/squid/access.log squid cache_dir ufs /var/spool/squid 1024 16 256 hosts_file /etc/hosts coredump_dir /var/spool/squid cache_mem 1024 MB cache_swap_low 94 cache_swap_high 96 maximum_object_size 16384 KB minimum_object_size 4 KB maximum_object_size_in_memory 2048 KB fqdncache_size 1024 acl snmppublic snmp_community public snmp_port 3401 snmp_access allow snmppublic all
