I've been wondering lately if it has something to do with Airline. I'm using its visible buffer display and when doing C-movement s between buffers it feels so terribly laggy (on a top of the line MB Pro). When switching via ctrlp everything is instantaneous, but that requires more commands than just C-k or C-j.
