API calls in a for loop (or not).

[Broken_Arrow]

Which one of the two methods (top or bottom) would you think is more efficient / best performance (faster)?

thanks in advance!

[AdnanZ]

The bottom one since Mean.vi is reentrant.

[smercurio_fc]

Of course in the top one you should be autoindexing the for-loop.

Excellent! Sometimes smaller / more compact isn't necessarily better.

Provided there are resource contentions and the parallel function play nice together, a bunch of parallel paths will almost always run faster on multi-processor machines.

If the CPU only has a single core, the results may be different (but that is a point that will quickly fall into obscurity).

Therein lies the crux. The technically correct answer to the question is: faster/more efficient under what conditions? Would the same hold for a single processor with hyperthreading? That's why I never too much stock in absolutes.
