Rt2.0 performance


I’d like to upgrade from rt1.0.x to rt2.0.
After installing rt2.0 i made some tests and relaized
that the performance of rt2 is not really usable yet.
to search 100 tickets at once hits the server quite a lot.
also sending 20 mails in short periods raises the servers load
up to 100!!!.

did i make any mistakes in installation or will performance be
optimized in future.

thank you in advance,
