### Description

There have been reports (See below) that Xamarin Studio 5.9 is behaving incredibly slowly, especially when typing into the editor. There can be a several second delay between typing and having it echoed in the editor.

There aren't any recent changes from my side which can explain that it's slow.

But I've noticed that it's very slow too - seems to be worse on os x. 

The good news is that I currently working on performance - the bad one is that I'm using the roslyn branch because that's way slower :/

btw. it would be helpful to know how much memory MD takes when that happens. It may be related to the memory leaking issues.

I never saw such a thing like in the video :/

I assume it's caused by the memory leakage.
