I was trying out the editor and felt it was a bit slow marking text. (I opened a normal stdafx.h file ~35 lines of code and marked some text). It was some kind of input lag not much but enough to catch my attention. So i wanted to see what the application drew in memory. Shocked i noticed that having a project opened with 5 tabs resulted in 5 atom processes taking up from 3.5mb in the smallest to 115+ mb as the largest.
Then i noticed marking text and just moving your cursor up and down e.g. marking more / less text made the process bleed allot of memory. And with allot i mean about 250KB / sec.
