[Building Sakai] Forums, Blog Wow and Wiki uselessly slow

[mizematr at notes.udayton.edu]

Gerwood,

We recently overcame a slowness across the board issue that was related to 
the hardware.  Our application server was running on a Sun UltraSparc 
T-Series architecture, which must not be compatible with Java threads.  We 
ran some benchmarks on various architectures and they showed using x86 was 
the best way to go.  We made the switch about three weeks ago and saw a 
40-60% performance increase across the board.

Hi Gerwood,

That sounds odd. Forums has some slowdown with large numbers of posts in a 
topic, but we've never seen any speed issues at all with blogwow or wiki.

I would look at database performance firstly (perhaps missing indexes?) 
and secondly at your JVM memory options (available memory, GC times, 
etc.).

Regards
Stephen

We are having a lot of issues with the speed (and thus usability) of the 
Forums, Blog Wow and Wiki tools.

It's bad enough that I don't believe most institutions using Sakai would 
be seeing similar results.

Does anyone know of what issues we might be encountering?

We are running on RHE boxes with an Oracle 10g backend.

Help would be greatly appreciated.

Thanks
Gerwood Stewart
