Grouper Users - Open Discussion List

[Philip Harle <>]

Hi,

Last year we migrated (via a fresh install) our instance of Grouper to 
version 2.2.2. Since then we have experienced a significant degradation 
around the speed of provisioning with the PSP. We've been using the PSP to 
incrementally provision groups since the upgrade, and accepted the reduced 
speed.

However, as we've recently loaded all student data for our new academic year 
into Grouper, the PSP has been working through over a quarter of a million 
changes. This is taking between 1 and 4 seconds for each change, and we're 
estimating that this could take anywhere up to 2 weeks to work through all 
the changes. The server itself isn't stressed and is showing low CPU and RAM 
usage. I've attached a small snippet of the grouper_error.log showing the 
groups currently being provisioned. Some of these are being published to our 
Active Directory, others are Grouper-only.

We're aware of performance issues with the PSP and the advice to upgrade to 
PSPNG in 2.3, unfortunately this isn't feasible for us at the moment. Hence, 
are there any configuration settings we should investigate/change in an 
effort to give some improved performance with the current PSP in the meantime?

Thanks,
Phil
