Performance less than 2 pages/sec

I install TWiki TWiki20030201.tar.gz on debian 3.0, with apache. I use apache "ab" (Apache Benchmark") to test it, I use WebHome as target in testing. Only 1 or 2 page per second comes out. The machine is PII 450, 256MB Ram.

Is such performace correct? Thank you.

Actually, you are getting good performance See CacheAddOn for more benchmark figures

TWiki is quite slow, as it is very dynamic and not much is compiled. I use a time wget -q -O /dev/null of the home page regularily, and what I found is that (on a PIII-800Mhz machine):

• Using modperl speeds a lot twiki (nearly ten times!). It can go from an unusable 4s to a really nice 1.2s. (on a PIII 800).
• Some plugins have real performance problems, even on pages not using them.

This is interesting: my assumption was, that mod_perl cuts the set-up time to zero, i.e.

• loading source
• compiling code
• opening permanent connections
• loading re-used files

Does TWiki keep file-handles open accross page calls, or how does this speed-up work?

This set-up is done on each HTTP request, so modperl helps there. Of course, modperl has no impact on the running of the perl code once loaded.
