Thread.Sleep(1) //so processor can rest for a while some other processing to do STILL POSSIBLE Combination: Stopwatch stopwatch = Stopwatch.StartNew() We could also use DateTime.Now or other means of time measurement, but Stopwatch is much faster (and this would really become visible in tight loop).įor 3. If (stopwatch.ElapsedMilliseconds >= millisecondsToWait) Tight waiting in C# is: Stopwatch stopwatch = Stopwatch.StartNew() However, windows thread scheduler causes acccuracy of Sleep() to be around 15ms (so Sleep can easily wait for 20ms, even if scheduled to wait just for 1ms).įor 2. Loose waiting in C#: Thread.Sleep(numberOfMilliseconds)

and preciseness + ability to do something of 2.įor 1. It usually combines processing efficiency of 1.Some actions can be performed while waiting.processor is VERY busy for the entire waiting interval (in fact, it usually consumes 100% of one core's processing time).No processing is possible on blocked/waiting thread.Executing thread blocks for given time (= does not consume processing power).There are basically 3 choices for waiting in (almost) any programming language:
