Ah, now you are getting somewhere!
You are attempting to tune your system for your own performance
requirements. Sorry to say it, but there is no silver bullet, no
magic wand, and we on the list don't have a crystal ball.
Tuning your system is work that you have to do.
BTW, if you don't have it already, here is a book that might interest you.
Brendan Gregg, Systems Performance: Enterprise and the Cloud, 2nd Edition

It won't solve your problem directly, but it might help along the way.
Good luck,
Richard
