I would use stopwatch but would need a loop
read this to add more extension to the stopwatch, like ElapsedMicroseconds
or something like this might work too
System.Diagnostics.Stopwatch.IsHighResolution MUST be true
static void Main(string[] args)
{
Stopwatch sw;
sw = Stopwatch.StartNew();
int i = 0;
while (sw.ElapsedMilliseconds <= 5000)
{
if (sw.Elapsed.Ticks % 100 == 0)
{ i++; /* do something*/ }
}
sw.Stop();
}
Very short sleep times are generally best achieved by a CPU spin loop (like the kind you describe). You generally want to avoid using the high-precision timer calls as they can themselves take up time and skew the results. I wouldn't worry too much about CPU pegging on the server for such short wait times.
I would encapsulate the behavior in a class, as follows:
- Create a class whose static constructor runs a spin loop for several million iterations and captures how long it takes. This gives you an idea of how long a single loop cycle would take on the underlying hardware.
- Compute a uS/iteration value that you can use to compute arbitrary sleep times.
- When asked to sleep for a particular period of time, divide uS to sleep by the uS/iteration value previously computed to identify how many loop iterations to perform.
- Spin using a while loop until the estimated time elapses.
