In one context an instruction will take a minimum of 2 clocks and in another context that same instruction could take 4 or more. Charts and tables etc really don't help. To optimise the performance you are best off to trust the optimiser in the compiler. Trying to hand optimize is a unique skill. To get a flavor of performance, write your test program in C or other supported HLL, turn on the Optimizer and let it run.
