Performance tuning depends on a lot of things.
How your client behave, ie, is it reusing connections or not?
How many simultaneous connections you have as your maximum?
From that you should be able to update the parameters according to:

If you have too many threads, the scheduler may have a hard time also.
Hope this helps,
