Dev Editor very slow on a Chromebook #3339

Performance of the Dev Editor on my Asus C200 chromebook is very poor. It's not really about the GUI performance overall because it's passable but the source editor is super choppy. Scrolling of a single source file (JS/HTML) consisting of less than 200 lines stutters a lot. Not only the scrolling is problematic. Also while editing a file the editor tends to crawl in some situations. For example copy paste operation sometimes produce a second or two lag. Typing is usually ok but there's a lag on a newline. Double clicking a word in the source to make a selection also lags and a selection is usually marked after a second or so. I know my device is pretty low end (Bay Trail CPU and 2GB of RAM) but I find performance of standalone text editors (Caret, Text) as well as online IDEs (Codio) much better without any scroll stuttering at all.

I can second that: the Ace editor is significatnly slower when it is running inside CDE compared to other projects using the same editing library (Ace). This is true for files that are not really triggering any special treatment inside CDE (js, html, unlike dart files that can trigger analizer etc).

Specific problem I see (even on i5 3.5 Ghz PC) is with double click - double clicking inside CDE triggers behaviour I have not seen in Ace before - it is supposed to do 'word select' and it does but becoase it is so slow sometimes CDE thinks I actually want to drag that code (i.e. move the selected text to a different place in the file) and this causes frustration when it does move it.

I also have been having problems. I recently have been having problems with the text selection, especially when I resume the app from the background. I'm using Chromebook Acer C720.

Chromebook Pixel here. Performance, especially while scrolling or selecting text, is quite poor. However, I remember it being better back in June.
