Performance of Unittests if you have plenty

[Niyol]

Hello,

First and foremost, I'd like to express my gratitude for your work on this framework.

I have a concern regarding the performance of unit tests, particularly when dealing with a large number of them. Presently, I have 90 unit tests, and the runtime for executing them is approximately 30 minutes.

As I intend to expand the test suite with more tests, it's becoming crucial to enhance the performance. One potential approach I'm considering is the ability to run test classes simultaneously.

Currently, I'm utilizing Xunit with the collection feature to execute all tests(one-by-one). However, I'm wondering if there are any additional optimizations I might have overlooked in this regard. Alternatively, are there any plans to implement features aimed at improving test execution performance?

Thank you for your attention to this matter.
