Test Runner Progress Bar Slow

I have nearly 4,000 tests to run. Individually they’re pretty quick, but ran through the test runner they’re really slow. As far as I can tell this seems to be linked to the DisplayProgressBar UI. In my own scripts, when I use a progress bar, I only update it every 1% change, this speeds up processes massively.

Is there an option to disable the progress bar, have it update less often, or something similar?

This is a really old issue, but might be still valid. @Gizmoi please DM me if you’re willing to share your project with us and I will check on performance issues related to the number of tests in it.
