Additional context
UPD by Penikov:
Just a little of details:
In addition, the bug is reproducing on Windows: Audacity crashes when I tried to apply Detach Silence after the Noise Gate effect
and on Mac Audacity raises an error:

I think the root cause of poor performance is duplicating the whole selection in every clip on the track.

In the video, I trying to show how Noise Gate works with many clips.

It is an overwhelming overhead. Also, it crashes audacity when Detach Silence tries to operate with trimmed clips.

And the combination of Noise Gate and Detwch Silence can crash Audacity even with one single clip in a project.
