maui-profiling

Repository for building MAUI apps over time using different versions -- for installing & profiling.

Results

These numbers were measured with preinstalled apps with scripts\profile.ps1 on a Pixel 5 device running Android 12.

** This is using the Preview 14 template built with MAUI RC 1. In RC 1, the template changed to use the shell navigation pattern and includes lots of built-in styles. It is a better template -- it just has more "stuff" in it. The old template's times should be a direct comparison between past releases.

NOTE: .NET 7 svc (servicing) is using .NET MAUI 7.0.96. I am using the same device from above benchmarks, but it has had several Android updates and is likely now aging. I reran one of these using the .apk saved here, and the number went from 545.4ms -> 558.8ms using the exact same device today.

• XamarinFormsFlyout: Xamarin.Forms Flyout template from VS 2022
• dotnet new android: literally run this command
• dotnet new maui: literally run this command
• .NET Podcast

In .NET 6, a project with -p:UseInterpreter=true includes libmono-component-hot_reload.so. I recorded some startup times for this, mainly as an experiment. This might be a view into what a tiered-JIT could look like?

FAQ

How to use scripts\profile.ps1?

If you don't easily know an apps package name & main activity:

1. You could open the .apk in Android Studio and look at the AndroidManifest.xml file.

2. Or run:

> adb shell 'dumpsys window | grep mCurrentFocus'
mCurrentFocus=Window{f372400 u0 com.myapp.foo/crc64362beeb2c8180c73.MainActivity}

Then you run the script such as:

> .\scripts\profile.ps1 -package com.myapp.foo -activity crc64362beeb2c8180c73.MainActivity

Register ADB with Powershell

You may need to create a powershell alias for adb:

Set-Alias adb "${env:ProgramFiles(x86)}\Android\android-sdk\platform-tools\adb.exe"

Or you can add the folder containing adb.exe to your %PATH%:

if ($env:Path -NotMatch "Android\\android-sdk\\platform")
{
    write-host "Adding Android SDK Platform tools to path"
    $env:Path += ";${env:ProgramFiles(x86)}\Android\android-sdk\platform-tools"
}

(Or use the Windows environment variable menu)
