Hi, I've seen notes that performance with processing large groups was a problem in FIM RC builds and was supposed to be addressed in RTM. How is it now? I'm currently trying to see how FIM Synchronization Service deals with large groups and how to design it properly. For testing I was trying to set up a simple scenario similar to MIIS/ILM and GroupBuilder - groups are built in SQL and synchronized to AD. I'm testing with a 100k member group, and just the delta import step from SQL (importing just the one group) took several hours. I'm running the delta sync now, and few hours passed already ... I'm wondering how the export to AD will be. My question is, bottom line, is there any hope in trying to use the standard MAs (SQL and AD) and FIM mechanisms to manage very large groups (like 100k-200k+ members)? Or it's a waste of time, and I need to be creative here. Piotr
