I don't really know, as I haven't looked into it much. But my vim config is in git and shared between Linux and Mac laptops. On Linux (2013 Thinkpad) I can't really detect much lag at all, but on the Mac (2015 MBPro) it's really quite annoying - to the point it subjectively seems about as "slow" as Atom. Interactive things like scrolling are especially annoying - non interactive things seem ok though. I'm no Vim or Mac OS poweruser though - I've just kinda put up with or avoided it. Sorry I couldn't really offer much beyond confirmation :)
