The slow undo is apparently a priority for developers

[Regnas (• I don't speak English "by default", so...)]

Are the developers aware of the incredibly slow undo and general slowness?

Not sure if this has always been an issue but it REALLY needs prioritizing. Once a scene gets to over something like 4m faces, it takes about 10 seconds to undo. In fact, lots of operations take 10 seconds. Like assigning and creating new materials. Please please no one say (because I know someone who’s been using 3d for a year will be reading this and about to reply)… but that’s what happens with large scenes, right? NO! I’ve been using 3d software since 1999 and have never seen a slow undo on…

Will something be done about Blender's slow undo system?

Blender 2.79 and 2.8 are both so slow performing undo when you have a heavy scene (a few million polies). Blender 2.8 even crashes when performing undos. Its gotten to the point where I’m scared of undoing. In other programs like max and Maya, Ctrl Z responds immediately, regardless of scene complexity. In Blender, a few million faces is enough to make it suffer. How do studios who build massive scenes in Blender manage this?
