We use the SP2010 FBA pack on an Intranet solution we built for one of our clients.
During development and internal test we had 10s-100s of users and found no issues with the FBA pack, however our client has 1000s of users and have reported performance issues with the user management page, in particular initial page loads and searching for
I've had a dig through the code and think the poor performance is due to the code retrieving all users when searching and then applying the filter in memory (i.e not passing the search parameters to the SPQuery). Are there any plans to improve this functionality?
We've seen the page take up to 20 seconds to load when using in the region of 3,000 users.
