The *pure* guy who managed to kill *ACS* in perfomance terms was me.
I'm working in aD Munich. Also i'm oracle (since 1995), scalability
and perfomace fanatic.
The sad results which i managed to *achieve* with testing scalability was:
1) using functions in sql (which procces number of rewos > 1)
2) usning null as criteria in where caluse (oracle diesn't include
null in indexes)
3) lame design of acs_messages and bboard
The permission datamodel design wasn't showstopper. the problem was
usage of it.
