Summary0007685: Cutting (splitting) regions too slow
DescriptionThere are 11 tracks (9 mono and 1 stereo) of recorded drums in the project.
I'm trying to do manual alignment of recorded drums, so I use "Cut mode (split regions)" tool for splitting recorded takes into short parts. After half of 0000009:0000005 minute song is done, cutting tool becomes incredibly slow. I really need to wait for minutes until regions become split into parts.

This really should be optimized because work with huge amount of regions becomes really slow and annoying.
TagsNo tags attached.

Here's the actual behaviour:

Is this only split? or region operations?

Is session-save also slow? How about scrolling and zooming?

Also can you try without any plugins that might interfere with Ardour's GUI idling?
