HiResStopWatch

High resolution stopwatch using RDTSCP.

Easy to use

procedureTForm1.Button5Click(Sender: TObject);
const
repeats = 1000000;
var
Timer: THiResStopWatch;
Time1, Time2: int64;
begin
Time1:= Timer.Sample(TimeInRange, repeats, EmptyProc);
Time2:= Timer.Sample(TimeCase, repeats, EmptyProc);
Memo1.Lines.Add(Format('InRange takes %d cycles',[Time1]));
Memo1.Lines.Add(Format('case takes %d cycles',[Time2]));
end;

TimeInRange, TimeCase and EmptyProc are simple procedures that look like:

procedureTForm1.EmptyProc;
beginend;

Accurate

Given enough repeats the timer is accurate to within 2 CPU cycles.
The timer knows about out-of-order execution and eliminates this issue as per Intel recommendations. The shorter the timing, the more repeats are needed.

1.000.000 is normal for single cycle timings.
100.000 for 100 cycle timings.
and 10.000 for 1000 cycle timings
etc.

If your code takes longer you might as well use the normal TStopWatch.
