Re: Problem with performance

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
