Chris Thorn writing for Thoughtbot: Lately, I’ve noticed that opening Markdown files in Vim is slow. I don’t know exactly how slow, but slow enough that I notice a pause after opening the file before I can edit it. I’m not sure why or when it started, but it’s painful enough that I want to track down and alleviate it. I, too, have felt this pain, which is one of the reasons I no longer use Vim as my full-time coding editor. I still use it enough for its sluggishness to bug me, but not quite enough to go chasing down why it’s sluggish. This article might change my calculus on that decision.
