Hi Wei,

Which particular platform? It just cross-compiled for me and runs on the
Nokia N900, though I agree it is quite slow.

Interesting, what in particular is causing the slow down? The use of fp
operations?

I'd be interested to help you with some optimisation work (though not until
next week probably).
