It is still true that numarray is at a disadvantage for small arrays.

I don't think there is a single array package that provides both PyFITS
and good small array performance. Consider porting your conversion code
to numarray and then profiling to get a better idea of the overall
performance costs of your application. If you find a specific hot spot
we can try to address it.
