Quick repo I'll use to profile build times on different Xamarin.Android projects
Just build either:
./build.sh
Or on Windows:
.\build.ps1
It will perform the necessary build steps/git operations and place the resulting MSBuild binary logs in ./output.
The following projects are setup so far:
BlankApp- File -> New Blank Android AppFormsBuildTime- File -> New Master Detail Forms templateEvolve2016- James Montemagno's Evolve 2016 app
The following logs are recorded so far:
-Clean.binlog- the clean build (after agit clean -dxfis performed)-Second.binlog- the second build after the "clean" build-TouchCS.binlog- modify a C# file and build after the "clean" build, adds//commenttoMainActivity.cs-TouchAR.binlog- modify anAndroidResourcefile and build after the "clean" build, adds<!--comment-->toResource/values/styles.xml
NOTE: NuGet restore is not included in timing
See the latest release for binary log files.
| Project | Clean Build | Second Build | Touch C# File | Touch Resource File |
|---|---|---|---|---|
| BlankApp | 6.271s | 1.618s | 2.074s | 1.769s |
| FormsBuildTime | 39.612s | 3.685s | 4.681s | 12.126s |
| Evolve 2016 | 1m 0.335s | 8.788s | 11.248s | 24.577s |
NOTE: this was with VS 2017 15.6.4, Intel 2.8ghz Core i7
| Project | Clean Build | Second Build | Touch C# File | Touch Resource File |
|---|---|---|---|---|
| BlankApp | 8.222s | 2.122s | 3.601s | 2.380s |
| FormsBuildTime | 34.196s | 4.401s | 6.542s | 12.467s |
| Evolve 2016 | 1m 24.588s | 16.218s | 19.791s | 36.206s |
NOTE: this was with VS for Mac 7.4.1 (build 48), should be equivalent to 15.6.4, Intel 3.3ghz Core i7
On the second build on Windows, for Evolve2016, IncrementalClean is deleting some proguard files:

After further research, it is fixed in Xamarin.Build.Download 0.4.9.
I forked the Evolve 2016 app, updated the NuGet, and reran the numbers.
