I just found out that ElapsedTicks in the Stopwatch class doesn’t mean real “ticks” if StopWatch.IsHighResolution is true. Note (if IsHighResolution is True – from Microsoft Connect link (now dead)): Stopwatch ticks are different from DateTime.Ticks. Each tick in the DateTime.Ticks value represents one 100-nanosecond interval. Each tick in the ElapsedTicks value represents the time … Read more
you could always do #do some stuff print ‘tasks done, now sleeping for 10 seconds’ for i in xrange(10,0,-1): time.sleep(1) print i This snippet has the slightly annoying feature that each number gets printed out on a newline. To avoid this, you can import sys import time for i in xrange(10,0,-1): sys.stdout.write(str(i)+’ ‘) sys.stdout.flush() time.sleep(1)
I’ve just written an article that explains how a test setup must be done to get an high accuracy (better than 0.1ms) out of the stopwatch. I Think it should explain everything. http://www.codeproject.com/KB/testing/stopwatch-measure-precise.aspx
You can query the properties Elapsed, ElapsedMilliseconds, and ElapsedTicks while the Stopwatch instance is running or stopped. The elapsed time properties steadily increase while the Stopwatch is running; they remain constant when the instance is stopped. — From https://learn.microsoft.com/en-us/dotnet/api/system.diagnostics.stopwatch.elapsedmilliseconds#remarks
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
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”))
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
