From Vim to Emacs
I began using Vim about a month ago and it has been totally revelatory to me, and believe quite honestly that it was the best career decision I've ever made.  The one thing, however, is its speed.  MacVim gets <i>very</i> slow sometimes, particularly with buffers.<p>So my question:  How does Emacs and Vim compare speed-wise?  I come from a Sublime Text background and really miss the ability to <i></i>quickly<i></i> navigate between tabs (buffers in vim), and sometimes it takes a full second.
