Start with the dotnet/performance benchmarking workflow and run the benchmarks_ci.py command for the SOD - Android HelloWorld Extracted Size filter. Compare the linked baseline and test reports for libcoreclr.so and libclrjit.so on Windows arm64, then use the referenced profiling and benchmarking documentation to determine what changed and confirm the extracted sizes no longer regress.
