Alexander,

All of the performance books you may one day read will tell
you that before you tune waits, first make sure your SQL is
good. That is, run explain plan (or any gui tool that will run
explain plan for you) and make sure the sql is using the
appropriate indexes, etc.

If all that works, then try increasing your buffer cache.

hth,

Yosi
