2.2GHz. Also bear in mind that it is probably keyboard repeat rate 
dependent - I don't know your keyboard repeat rate.

It's also possible the relative perf between cpu and gfx is different on 
my system.

And were you testing on w32 or x11? After all, while the redisplay code 
path is partially shared, the font rendering layer is different between 
the two. I was using the latter, I didn't think to stress that in later 
posts.
