Re: Delayed response for sleep function

There will always be a delay between measurement and observation, 5-6 ms does feel a bit high for the functions you’re calling. 

I’d time the execution of the functions you’re calling, averaged over many runs, to see if there is a bottleneck somewhere. 

I’d also check to make sure that your optimization level is 2 or 3.
