Single file application slow on osx-x64 runtime

[thomhurst]

I originally thought this was a dotnet runtime issue but a single file executable basic console app is quicker on all runtimes than invoking dotnet run.

However once you add the Microsoft.Testing.Platform then a osx-x64 single file executable takes a lot longer.

Benchmarks are here: https://github.com/thomhurst/SlowOsx64SingleFile/actions/runs/10811251824

Basic reproduction is available in that repository too.

Do you know if this reproes only on M1 or also on Intel chip on MacOS?

Don't know off the top of my head. Whatever the GitHub actions macos-latest uses

the benchmark you shared run on M1. Thanks.

still observable.

Interesting, I am wondering if we should ping some people from runtime so we could maybe have some pointers on what could have such big impact.

That was the original thought, but it only reproes when our packages are added, so I guess we need some traces at least, before bothering runtime people, postponed till my wife lends me her Mac 😁
