No, it was in my config. In emacs -Q the difference isn't as stark and
it's quite a bit faster which has me wondering what the heck in my
config could slow things down that much.

line numbers: 1.54s
no line numbers: 1.37s

Only 12% difference there, which is still something but not the 30% I
was seeing on my config.

The file is a private ruby file that's copy pasted enough times to
make it 11k lines long. I was using enh-ruby-mode with my config but
regular ruby-mode doesn't make any difference.

I'll see if I can track down what makes such a big difference in my config.
