This is the most disappointing and WTF thing for me… I really don’t understand why Node.js and Webkit were chosen if they want to compete with a performant native text editor (Sublime) and bloated IDE’s (Eclipse).
When selecting a few paragraphs of text, the selection lags several lines behind my mouse! Scrolling is slow and switching between tabs is slow. And I mean slooowwww. On my machine (Thinkpad T440s), Eclipse is faster! Eclipse scrolls faster, switches tabs faster, selects text faster. And it has autocomplete. If Eclipse can outperform Atom at editing text files, then I think there’s a serious problem.
