Question

I have customized TWiki almost how I want it, after alot of changes. The only things left are performance tuning and design touch-ups. I am finding that after I applied mod_rewrite to get ShorterURLs the performance of my TWiki has dropped alot. It now takes upwards of 40 seconds for it to merely respond to my browser and send the web page. Is there anyway I can figure out what is causing this huge delay, TWiki or mod_rewrite or some other source?

I plan on trying out the chaching plugin after this, but first things first...

Thanks for any answers.

Update: I just took the time to time the web pages about a dozen times, and each time it took exactly 30 seconds before apache returned any data to my browser after requesting a page. Is there some problem that is causing apache to stall or timeout after 30 seconds? Nothing in apache's error or access logs.

Answer

No idea what the problem is, but it would be worth testing without the mod_rewrite stuff, and your customisations (separately). Even on a PIII/800 using Linux, most pages are rendered in a few seconds, in my experience. See TWikiDebugging for some ideas.
