Ouch!  I just tried it here and performance was also bad (~2 seconds
to display, but scrolling one page right then took 14 seconds!).
That's using the gtkextra "table" widget.  (I hadn't noticed it being
very slow before... perhaps recent changes have hurt it?)

Configuring "--without-gtkextra" still takes 1-2 seconds to initially
display the table, but then scrolling is effectively instantaneous.
Perhaps we'd be better off without GTK+extra...

Less than 1 second here.  (Most of that time is probably spent rendering
the board preview.)

Too fast to measure (1/10 second?) once the evaluations are cached.

Yes, this is disappointing news... is GTK+ 2 always this slow on MS
Windows?  Does performance vary if you try different themes?  Was the
"gtk-demo" program built when you installed GTK+?  If so, how well
does that run?

1300MHz Celeron, 128MB RAM, Intel 810 video, XFree86 4.2.0, GTK+ 2.2.0
with a moderately graphics-intensive theme and GDK_USE_XFT=1, and
random assortments of GNU/Linux system stuff (it's got a new handle and
a new head, but it's still a Slackware 8 axe) here.
