I use it often on a huge UML diagram (~334 classes), mainly to navigate to the class I need to work on.  Scrolling at anything smaller than about 30% magnification takes too long.

And while I'm on that subject, is there anything I can do to make scrolling at low maginfications faster?  I realize I'm not running such a fast machine (900 MHz Via C3 w/ 256M), but Acrobat Reader on the same machine can really zoom around similar diagrams and the same is true of ERwin on my dual 350 MHz P-II, so it seems like it should be possible, at least in theory.

I keep meaning to really investigate scrolling performance with gprof (any recommendations other than gprof?), but haven't gotten to it yet.
