BlazorWasmProfiler

Poor Man's Blazor Wasm Profiler

It uses AspectInjector to time the execution of every method in your Blazor WASM project.

It also measures the render time of every Blazor Component that defines these methods:

    protected override void OnParametersSet()
    // or
    protected override async Task OnParametersSetAsync()

    // and

    protected override void OnAfterRender(bool firstRender)
    // or
    protected override async Task OnAfterRenderAsync(bool firstRender)

How to use:

1. Include NuGet package from https://www.nuget.org/packages/BlazorWasmProfiler

    <ItemGroup>
        <PackageReference Include="BlazorWasmProfiler" Version="0.0.1.0" />
    </ItemGroup>
   

2. Add the attribute somewhere in your code

    [assembly: BlazorTimer]
   
    [assembly: MethodTimer]
    [assembly: RenderTimer]
   

3. Access statistics

    var methodStatistics = BlazorTimerAttribute.GetMethodStatistics();
    var renderStatistics = BlazorTimerAttribute.GetRenderStatistics();
   
    var methodStatistics = ExecutionStatistics.GetMethodStatistics();
    var renderStatistics = ExecutionStatistics.GetRenderStatistics();
   

4. (optional) Use MethodCallStatistics and RenderTimeStatistics as components

    <BlazorWasmProfiler.MethodCallStatistics />
    <BlazorWasmProfiler.RenderTimeStatistics />
   

5. (optional) Change

    <Router AppAssembly="@typeof(App).Assembly">
   

   to

    <Router 
        AppAssembly="@typeof(App).Assembly" 
        AdditionalAssemblies="new[] { typeof(BlazorWasmProfiler.BlazorTimerAttribute).Assembly }">
   

   and use MethodCallStatistics and RenderTimeStatistics as pages

    <a href="MethodCallStatistics">Method Call Statistics</a>
    <a href="RenderTimeStatistics">Render Time Statistics</a>
