FWIW, I did some subjective tests with scrolling large amounts of data 
in Rev vs. Word, Excel, and others. Rev outperformed them all, quite 
noticeably.

So if it seems slow, try the same size data anywhere else.  Sometimes a 
lot of data just takes a long time to redraw.

Fortunately the user will likely resize a window infrequently.
