Hello
I am running Squid 2.5 Stable 6 on a Pentium4 1.8 Ghz and 256 Mbytes RAM.
am trying to put this proxy in a production environment soon, but,although
squid is performing just fine all tasks, when I began to try the ACLtests,
squid.it seems to slow down (very much) when a blacklist file is loaded. The configuration is the following:
acl denegar url_regex "/opt/squid/blacklist"
This blacklist file has 25000 sites on it, and it seems to take down
I don't know if you guys can provide me some tips so I can tune up mysquid
proxy. Can you tell me if I am using the wrong hardware configuration, ifI
need more RAM, or if I just have to change some stuff in the squid.conf file.
I'd appreciate your help
Regards
Pablo Romero
url_regex is a last resort, and very CPU intensive. Use dstdomain instead in any instance that you can (i.e. instead of "url_regex site\.domain" use "dstdomain .site.domain") and you'll find performance improves greatly.
