This question about Upgrading from TWiki to Foswiki: Answered

Performance Issue

Recently I discovered a performance loss with foswiki. Then I discoverd in an error message following entry:

[Mon Dec 5 09:35:55 2011] [error] [client 10.1.3.46] script not found or unable to stat: /usr/lib/cgi-bin/twiki

The described location exists not anymore. I think it was part of TWiki but is not in use anymore.

It is unclear for me what tries to access it. Does anyone has a hint for me?

Kind Regards

Andreas Koch


Its probable that your apache access.log will tell you what the referring url is that triggers the request to twiki. if the referrer entry is empty, then someone or something is accessing the url directly - bookmark or similar

however, its unlikely that this is the source of the preformance loss :/ - for that we will need some more info.

Hi, thanks for the information. You might be right that this is not the source.

Hi Andreas,

We have noticed many users report improved performance when they switch their {Store}{Implementation} from RcsWrap to RcsLite. See Tasks.Item11476.

It's also very important to make sure you've configured apache to serve static (.css, .js) files in a way that is properly cached in the web browser, to prevent 70 different HTTP requests being made for each view.

Finally, there is some code in Foswiki which takes advantage of persistent perl environments (Eg. mod_perl or mod_fcgid), so it's definitely worth configuring apache to use mod_fcgid to get a bit of extra performance.

Some details about this stuff is at PerformanceSupplement
