Bad UI performance with many modules loaded

[informatorius]

dnSpyEx version

6.5.1

Describe the Bug

I got bad UI performance with many modules loaded. Callstack of dnspy shows it updates Command.CanExecute in UI thread on any mouse click. But it does not return just a true or false value. But sync calls into DocumentTreeView and updates all nodes.

Expected behavior: Update DocumentTreeView async and send event to UI when finished to update Command.CanExecute from a bool value.

Also it seems this DocumentTreeView update happens too often or is uncached.

And using parallel.foreach or Linq.AsParallel() may distribute the node updates and search to more CPU cores for faster results.

How To Reproduce

load many modules and search for a string or debug

Expected Behavior

Actual Behavior
