Improvements in garbage collector usability

I agree with @caiopsouza in the sense those changes don't seem to make a huge difference. Ideally, any kind of optimization like that should be validated, so you could even tell in the end by what amount your change had reduced allocations... You can use BenchmarkDotnet to help you out in this.
