Performance and bugs on Linux Mint

Dotnet sdk version: 3.1.100
Unit test framework and relevants versions of that: xUnit
OS: Linux Mint 19.3

Hi,

The extension works perfectly on Windows, but on Mint I have some issues:
- Tests take too long to execute.
- Test discovery takes much longer than on Windows (the consume of CPU is almost the same, but this is an issue already reported a lot of times and it seems to have something to do with the dotnet sdk itself).
- If I stop a debugging test using Shift+F5, the spinning icon never stops and then I have to restart Visual Studio Code.

Is it just me having those issues on Linux?

Thanks!

Eric
