See my other message: I did compare with it, of course, but the
performance was very poor.  Maybe it wasn't supposed to provide a
great performance in a file like xdisp.c.  Or maybe my benchmark is
skewed (in which case I'm sure you will provide a better one).

The fact that the numbers are always displayed on the left is bad
enough; worse, the digits in the numbers are in reverse order.  E.g.,
visit TUTORIAL.he, then turn on linum-mode or nlinum-mode, and watch
the numbers closely.
