I haven\'t ever seen it running on a C760 but I haven\'t heard that it is particularly slow. Maybe someone who has used it under Qtopia on a C760 can comment? I did offer to re-compile opie-reader for the xscale at one point but the person I offered said that it was fast enough without that little bit of extra optimisation.
It should be possible to pre-prepare the next screen load of info in the background (that is what I used to do on the epoc version) but as I hadn\'t had adverse comment about page down I haven\'t bothered (page up is another matter, though).
There have been big differences in performance depending on how QT refreshes the screen. Maybe QT under X11 is less efficient, or lazier, about doing screen refreshes? It works okay in fullscreen on my 400MHz laptop at 1280 x 600 which is 10 times the resolution with a not much more powerful processor (Crusoe vs XScale?).
I believe Sash is going to have a go at compiling it. Maybe he knows some magic optimisation options which will help. If not I\'ll see about adding some extra instrumentation so we can see what is happening.
Unless you are using ppms format or lots of graphics the type of document shouldn\'t matter too much.
