Well, of course, the Electron framework, which is essentially a stripped down Chrome browser, consumes more hardware resources than a terminal-based text editor. On my machine (Core i5-4590, no extra graphics card, 8 GB memory), once it's open (which takes a while), it's nevertheless very fast and definitely not sluggish.
