Most common hardware does not have a particularly high resolution RTC, 
so the limitation occurs even below the software level.

I'd guess your best bet would be to use the benchmark module and call
your code in a loop a couple of million times. You'll need to write a
stubbed version that has just the entry point and a return. Time that 
too, and subtract the result from the value for the real routine to
find out how much time your actual code is taking.

(But I bet I'm just teaching you to suck eggs, here, aren't I ;-)
