Any modern day server should be able to handle your SER requirements quite easily. I would try to increase the SER children to see if it helps.
I have heard of stats as high as 2000 call setups per minute on a high end box. So a few hundred registers per second should be easy to handle. Unless of course your MySQL database is many milliseconds away.
