What is the best way to measure execution time of a function

Question

Obviously I can do  and DateTime Now After - DateTime Now Before but there must be something more sophisticated   Any tips appreciated

I would definitely advise you to have a look at System.Diagnostics.Stopwatch

And when I looked around for more about Stopwatch I found this site;

Beware of the stopwatch

There mentioned another possibility

Process.TotalProcessorTime

Tickcount is good  however i suggest running it 100 or 1000 times  and calculating an average   Not only makes it more measurable - in case of really fast short functions  but helps dealing with some one-off effects caused by the overhead

Use a Profiler  Your approach will work nevertheless  but if you are looking for more sophisticated approaches  I d suggest using a C  Profiler    The advantages they have is    You can even get a statement level breakup No changes required in your codebase Instrumentions generally have very less overhead  hence very accurate results can be obtained    There are many available open-source as well

System Environment TickCount and the System Diagnostics Stopwatch class are two that work well for finer resolution and straightforward usage   See Also    Is DateTime Now the best way to measure a function   s performance  High resolution timer in  NET Environment TickCount vs DateTime Now What   s the best way to benchmark programs in Windows
