Grouper Users - Open Discussion List

[Peter DiCamillo <>]

I'm working on putting Grouper 1.6.1 into production as an upgrade from 
1.3.  Things were going fine until I started to load a lot of data into 
the database, and now I'm seeing a performance problem.  With our full 
database in Grouper 1.3, we can add or delete a few people per second 
from a typical group.  With Grouper 1.6.1, the same operations on the 
same groups have a rate of about 3 seconds per person, which is about an 
order of magnitude slower.  With 1.6.1, performance has gotten worse as 
more groups are loaded, and I'm getting that performance with less than 
half the database loaded.  We're using an Oracle database, and LDAP as 
our person source.

Since performance was fine when I first started to load the database, I 
suspect that the problem is related in some way to the database.  Any 
obvious things I should check in a new Grouper installation that might 
affect performance?  Any suggestions on how to start tracking down the 
source of the delays?  Thanks for your help.
