You'll never find the 'exact configuration' for the OP's system - even on the OP's site. 15 minutes after it's installed, it's probably changed.

Applications are what we tune.

One can. Many do.

At least TCP attempt to hold some of them (such as type & qty of workload, type of app) constant to give the analysis a bit of an even keel.
