High-Performance Timer vs StopWatch
Stopwatch is based on High resolution timer (where available), you can check that with IsHighResolution

Elapsed.TotalMilliseconds (double) returns the total number of whole and fractional milliseconds elapsed since inception e.g. a stopwatch stopped at 1.23456 seconds would return 1234.56 in this property. See TimeSpan.TotalMilliseconds on MSDN Elapsed.Milliseconds (int) returns the number of whole milliseconds in the current second e.g. a stopwatch at 1.234 seconds would return 234 in this property. … Read more
The Stopwatch object is often used to (as you do here), measure how long things take. One quick thing to remember here is that it will take the time for everything you do between starting and stopping it, so make sure you only put the actual code you want to time between those. using System.Diagnostics; … Read more
To avoid future problems with a timer, here is the right code: timer = new Timer(); timer.Tick += new EventHandler(timer_Tick); timer.Interval = 1; //set interval on 1 milliseconds timer.Enabled = true; //start the timer Result result = new Result(); result = new GeneticAlgorithms().TabuSearch(parametersTabu, functia); timer.Enabled = false; //stop the timer private void timer_Tick(object sender, EventArgs … Read more
The Stopwatch isn’t doing anything between the calls to Start and Stop… It just stores the current timestamp (via QueryPerformanceCounter) when you start it, and compare it to the current timestamp when you stop it. So there is no reason it could affect the performance of your code, at least not significantly. Stopwatch was designed … Read more
You should use: ts.ToString(“mm\\:ss\\.ff”) this will give you minutes, seconds and the hundredths of a second in a time interval. also take a look at http://msdn.microsoft.com/en-us/library/ee372287.aspx EDITED: well if you want minutes be your biggest unit you can do the following: string.Format(“{0}:{1}”, Math.Floor(ts.TotalMinutes), ts.ToString(“ss\\.ff”))
Under the hood, pretty much all Stopwatch does is wrap QueryPerformanceCounter. As I understand it, Stopwatch is there to provide access to the high-resolution timer – if you need this resolution in production code I don’t see anything wrong with using it.
As per MSDN: The Stopwatch measures elapsed time by counting timer ticks in the underlying timer mechanism. If the installed hardware and operating system support a high-resolution performance counter, then the Stopwatch class uses that counter to measure elapsed time. Otherwise, the Stopwatch class uses the system timer to measure elapsed time. Use the Frequency … Read more
I would suggest using TimeUnit. You can use it like this: long minutes = TimeUnit.MILLISECONDS.toMinutes(millis); long seconds = TimeUnit.MILLISECONDS.toSeconds(millis);
No, you don’t need to stop it. Stop() just stops tracking elapsed time. It does not free up any resources.
