HI
I am using Redhat linux 9.0 and using squid proxy server.My problem is tht i my squid server is responsing very slowing. whenevr i try to open sites the site starts to open after 3 or 4 seconds and often squid does not open the complete site. its stop the site in middle. My squid Configurtion is below. Is there any need to tune the system parameters Like from 'SYSCTL.conf' for better diskd performence or another problem. at this time i am using default system parameters. Please help me in detail what is the reason of squid slow performence if there ia a need of any system tuning please tell me in detail. I am very thankfull to you.I am really worried about slow performence of the squid. I also try to offline_mode on but the same problem.

If you're squid has been running a while, sometimes it helps to clear the cache. I believe that is the -z option. Also you seem to have alot of regex statements. I would recommend squidGuard for a blacklist helper, rather than too many complicated regex statements that you may not understand.

Also, if you are dealing with Adults rather than children, I've found it is more effective to write a program to parse the access log, then e-mail alerts, than it is to try to keep up with a comprehensive blacklist. Squid runs faster too, since it is not filtering.

Once Adults know they will be accountable, and that a machine may e-mail an embarrassing alert to their supervisors and or colleagues, then suddenly there is less filtering to do.

Hi..

run the below command & send me the output.

squidclient mgr:info
