What is the best place to start with in cache analysis? Would it be cache size, memory object size, IO, etc.? I'm looking to optimise the settings for my squid server. Server: about 220GB available for the cache, I'm only using 40000 MB at present as in the config below. system D2812-A2 /0 bus D2812-A2 /0/0 memory 110KiB BIOS /0/4 processor Intel(R) Core(TM)2 Duo CPU E7300 @ 2.66GHz /0/4/5 memory 64KiB L1 cache /0/4/6 memory 3MiB L2 cache /0/4/0.1 processor Logical CPU /0/4/0.2 processor Logical CPU /0/7 memory 3MiB L3 cache /0/2a memory 1GiB System Memory /0/2a/0 memory 1GiB DIMM DDR2 Synchronous 667 MHz (1.5 ns) /0/2a/1 memory DIMM DDR2 Synchronous 667 MHz (1.5 ns) [empty] /0/2a/2 memory DIMM DDR2 Synchronous 667 MHz (1.5 ns) [empty] /0/2a/3 memory DIMM DDR2 Synchronous 667 MHz (1.5 ns) [empty] /0/1 processor /0/1/0.1 processor Logical CPU /0/1/0.2 processor Logical CPU Current squid.conf: --------------------- auth_param basic realm Proxy server auth_param basic credentialsttl 2 hours auth_param basic program /usr/lib/squid/ncsa_auth /etc/squid/squid_passwd authenticate_cache_garbage_interval 1 hour authenticate_ip_ttl 2 hours acl all src 0.0.0.0/0.0.0.0 acl manager proto cache_object acl localhost src 127.0.0.1/255.255.255.255 acl cacheadmin src 88.xxx.xxx.xxx acl to_localhost dst 127.0.0.0/8 acl SSL_ports port 443 acl Safe_ports port 80 # http acl Safe_ports port 21 # ftp acl Safe_ports port 443 # https 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 1863 # MSN messenger acl ncsa_users proxy_auth REQUIRED acl maxuser max_user_ip -s 2 acl CONNECT method CONNECT http_access allow manager localhost http_access allow manager cacheadmin http_access deny manager http_access allow ncsa_users http_access deny !Safe_ports http_access deny CONNECT !SSL_ports http_access deny to_localhost http_access deny maxuser http_access allow localhost http_access deny all icp_access allow all http_port 8080 http_port 88.xxx.xxx.xxx:80 hierarchy_stoplist cgi-bin ? cache_mem 100 MB maximum_object_size_in_memory 50 KB cache_replacement_policy heap LFUDA cache_dir aufs /var/spool/squid 40000 16 256 maximum_object_size 50 MB cache_swap_low 90 cache_swap_high 95 access_log /var/log/squid/access.log squid cache_log /var/log/squid/cache.log buffered_logs on acl QUERY urlpath_regex cgi-bin \? cache deny QUERY refresh_pattern ^ftp: 1440 20% 10080 refresh_pattern ^gopher: 1440 0% 1440 refresh_pattern . 0 20% 4320 quick_abort_min 0 KB quick_abort_max 0 KB acl apache rep_header Server ^Apache broken_vary_encoding allow apache half_closed_clients off cache_mgr aaa@xxxxxxx cachemgr_passwd aaa all visible_hostname ProxyServer log_icp_queries off dns_nameservers 208.67.222.222 208.67.220.220 hosts_file /etc/hosts memory_pools off forwarded_for off client_db off coredump_dir /var/spool/squid _________________________________________________________________ Do you have a story that started on Hotmail?
