Create user and group add takes extremely long

Hi using Open fire 4.3.2 internal BD on Windows server 2008 R2 , like title says its taking forever to create and add a user to a group.

Are you referring to shared rosters? If so, this is a known issue that is being investigated.

Not sure about shared roster function, I’m kind new with spark, the problem that i have is exacly when i try to create a new user then try to add him on a new group, the tab keep loading and take alot to add him
