Question

Twiki installation is too slow. I have adequate space on disk and lots of RAM but even then Web/topic access is too slow specially when there is lots of content in a web or topic is large. I have also noticed that Twiki.org is also one of slowest sites on net. Any keys to boost performance.

See PerformanceSupplement.

If you can accept lowering the featureset, disabling internationalization settings and switching to classic skin each gives measurable gains.

What timings do you get? (You can measure with i.e. ApacheBenchmark).

I ran Apache benchmark for 8 concurrent requests for around 600 seconds, I get following times :

Don't do that! You will loose contact to your server!

They do look a bit to the bad side these timings. For regular 2-3ghz pentium hardware TWiki will answer a non-complicated request in between 1 and 2 seconds, so 8 concurrent threads should lead to something like 16 seconds response time on average (or a bit less).

But try enabling speedycgi (or one of the other accelerators) and perhaps follow suggestion on i18n / classic skin; these are the major things you can do (will ~half your reponse times easily).
