Could be, if your threads are fast.
Remember that these days, 1ms == 2 to 3 million instructions.

What drives the threads?
There might be a delay in the code that starts the theads, so it
starts a bunch, then sleeps for a bit. There are other process
running, so the main code can't keep starting threads without pauses.
As an experiment, you might bump up the starter's process priority.
See:  SetPriorityClass()  and  SetThreadPriority()

You might try GetSystemTime().
You could also look into QueryPerformanceCounter()

	LARGE_INTEGER    start, stop;
	QueryPerformanceCounter( &start );
	{do your thread stuff}
	QueryPerformanceCounter( &stop );
	{log  stop - start }
