Good afternoon

I'm working on Grouper at Newcastle University where we've been running 1.6.3
for many years now. We're planning to upgrade to 2.2.2 soon, with real time
PSP provisioning to AD backed up with a bulkSync overnight.

In the testing we've done so far, the bulkSync consistently takes about 6
hours to run which is a lot longer than we'd like. We've tried various things
to speed this up, including increasing the available memory and adjusting the
settings in ehcache.xml (as described in training video 4,

Our current 1.6.3 setup takes about 2 hours to provision to AD using the old
ldappc method, so 6 hours seems like a very long time to us. Does anyone have
any suggestions of how we can reduce this, please?

Thanks in advance for any help!
