Comment 4 for bug 361843

I have also noticed a slowdown in text-editing. I did not change the font style and still text highlighting is sometimes painfully slow and the characters appear or disappear with quite a lag after the key stroke. One more point I noticed is that the autocomplete function for latex commands is _very_ slow. I use only a customized file for completion which is not more than 200 commands long and since I switched to v2.1 I am usually faster just typing the whole command than waiting for autocomplete to come up with a suggestion.
