GNOME Shell Picks Up Performance Improvements For Extensions

[tildearrow]

The extension system imho should just be removed or restricted to only a few areas (e.g. adding things on the top status menu).

That'd make the desktop even less flexible, and after that I'm pretty sure many would move away from it...

Is the problem that all extensions run within the main UI thread being addressed, or is that too disruptive a change that will have to wait until GNOME 4?

Good question. Sounds difficult to me. JS is still single-threaded, isn't it?

Mutter is written in C, not JavaScript. And Gnome-Shell itself is also partly implemented in C, so the language is not the barrier.

Way too disruptive. You can read a related proposal for "GNOME Shell 4" here, outlining the changes that need to be made.
