Presentation

EasyProfile is a cross-platform profiler using .NET Standard 2.0. It runs anywhere you have C# installed. It provides a simple way to profile your code without having to pay for a version of Visual Studio with a .NET profiler. You can use it in two different ways. You can either write the code to profile in a using block or between a Start() and Stop() function.

using version:

using
{
    //Code to profile
}

Start() and Stop() version:

Start();
//Code to profile
Stop();

The profiler also comes with two modes: a dynamic mode and a static mode.

Dynamic mode

In the dynamic mode, EasyProfile automatically updates to the Console the statistics of utilisation.

Static mode

In the static mode, you'll have to call a function when your done profiling your code. The data will be written to a file in a format that makes it possible to be view in any chromium browser. You'll simply have to type chrome://tracing and load the json file generated

Warning: the static mode is still in development, only the dynamic mode works at the moment

How To use

The profiler automatically creates the dependency tree to know in which section it is called. The dependency tree is built the first time of the execution adding a bit of overhead. But after this first building step, the profiler becomes low overhead.

Dynamic mode

You can profile your code and having results displayed at regular intervals using either of the two methods:

using (EasyProfile.Profiler.DynamicProfile("Section1 Name"))
{
    /*
        code to profile
    */
}

EasyProfile.Profiler.DynamicStart("Section1 Name");
/*
    code to profile
*/
EasyProfile.Profiler.Stop();

The difference between the two methods is that with the using, the profiler automatically stops if a return happens in the using block. With the Start and Stop method you'll have to be sure that for each Start call, a Stop call is made for each path in the profiled code.

By default, the statistics are displayed on the console each second. You can change this behaviour by calling

EasyProfile.Profiler.DynamicTimeInterval = /*time in second (integer)*/

Nested sections can be created. While in a using block or after a Start call without encountering a Stop call, the profiler will create a new section as a child of the current one and they will be indented in the display in the console.

For exemple, this code

void ProcessAudioData()
{
    using (EasyProfile.Profiler.DynamicProfile("FFT"))
    {
        PerformFFT(/*...*/);
    }
}
//...
using (EasyProfile.Profiler.DynamicProfile("Read Audio Data"))
{
    ReadAudio(/*...*/)
}

//...

using (EasyProfile.Profiler.DynamicProfile("Process Audio Data"))
{
    ProcessAudioData(/*...*/);
}
//...

Will display:

The format of the display is as follow:

<section name>: <call number> in <total ms time>ms (<time / call>)
    <section name>: <call number> in <total ms time>ms (<time / call> - <% of parent section if any>)
