AutoEdit slows down editing of large documents [message #1062905]

It seems that editing of large documents is delayed by the autoedit module. I've attached an image containing the profile results when hitting "Return" at the end of a large document.

index.php/fa/15229/0/

My question is if the autoedit module could be optimized in future versions of xtext?

I'm using the following grammar:

grammar org.xtext.example.mydsl.MyDsl with org.eclipse.xtext.common.Terminals

generate myDsl "--------"

Model:
	greetings+=Greeting*;
	
Greeting:
	{Greeting}
	'Hello' '{' 
		name=ID? '!'?
	'}'
;

And the document looks like this(8000 lines of code):

Hello {
	world!	
}Hello {
	world!	
}Hello {
	world!	
}Hello {
	world!	
}Hello {
...

Niek,

we'd be more than happy to accept patches which improve the performance
of autoedit. Could you please file a ticket with your findings?

Regards,
