Should ST2 be able to edit a roughly 2 meg source file? I'm looking at some js source from this blog post (specifically, this file: https://sites.google.com/site/simontechblog/home/sh-lighting/shLighting.js). It's big due to a few large embedded data arrays.
On my computer with a stock ST2 build 2144 (no plugins, etc), I can move the cursor at about 2 fps, making editing pretty much an impossibility. Is this expected?
