[squid-users] Low Hit Rate
Hi, I've recently installed Squid 2.7 Stable on Centos 5 and experiencing an extremely low hit rate at approximately 5%. If I tail the access log I see a lot of TCP_MISS, and looking at the store log I see a lot of RELEASE and very little SWAP_OUT. Any ideas how I can go about diagnosing the problem? Mark
RE: [squid-users] Low hit rate
Kemi, I increased my hit ratio by running pages and script output through a cacheability tool and taking corrective action as required. The main thing was to add mod_expires and mod_headers to my servers. http://www.cacheflow.com/technology/tools/friendly/cacheability/index.cfm John Kent Webmaster Naval Research Laboratory Monterey, CA -Original Message- From: Duane Wessels [mailto:[EMAIL PROTECTED] Sent: Saturday, February 14, 2004 4:47 PM To: Kemi Salam-Alada Cc: [EMAIL PROTECTED] Subject: Re: [squid-users] Low hit rate On Sat, 14 Feb 2004, Kemi Salam-Alada wrote: > Hi all, > > How can I tune my squid so that I can generate high hit rate?

[squid-users] Low hit rate
Hi all, How can I tune my squid so that I can generate high hit rate? Presently, I am running squid using FreeBSD 4.3 OS and Squid 2.5 STABLE2. The file system used for the disk is aufs. Regards.
