Well, here is a profile for Mac. I created a new document with

Very nice Bennett but, unfortunately I am missing one level at this

As you can see in the second line, QLPainter::text() take the most
time. This is not surprising but the following lines between this
node an the following node at the same level (LyXText::getFont())
don't make the sum. There's some info in between that is missing.
Could you please (when you have time) have a look at it?
There's no info I have that you don't have. (Doesn't that mean that
QLPainter::text() is eating up more than 10000 ms or so all on its own?)
To confirm this, I've run the profile again. I've put a screen shot
of Shark's output here:
<http://edisk.fandm.edu/bennett.helm/LyX/lyx-mac-150-profile-2.jpg.zip>
(This one is even worse: QLPainter::text() eats up over 17 seconds
out of the 30 second profile -- if I understand it correctly.)
