There is no performance bugs per se in the grammar. And also, the  
parsing is asynchronous, so it is not the parsing itself which stalls  
TextMate.

Likely it is resolving scope selectors, this is done both when  
building the function pop-up and when rendering the text.

The first there is not much to do about, the second might improve if  
you disable all the bundles you do not use (so less bundles provide  
styles/preferences where the scope selector needs to be compared) --  
FYI what’s actually slow here is using the system string class. I am  
switching away from that, but not in the 1.5 branch (which is really  
just for bug fixes).

Could you btw let me know which machine you have?
