[GE users] ge 6.2u5 issues

We recently upgraded our ge hardware and software from:
2 core /4GB sol10u4 system with ge 6.0u8
4 core/16GB sol10u8 system with ge6.2u5
the ge manages ~ 220 nodes and ~ 1100 cores
1) If a single user submits 100's to 1000's of jobs the ge commands (qstat, etc) hangs for minutes until all the submitted jobs are scheduled to either run or wait.
After this "hang" responsiveness is back to normal
This does not seem right. Is there a way of tuning the scheduler to schedule jobs and still let qstat and other commands function without these delays?
2) our current ge instance running only 1 cell runs at 11 GB - 12 GB of memory usage. This seems like a lot of memory , especially since we used to us < 4 GB.
Is this expected? Are there tunable controls to manage memory usage?
