We did some more profiling (see the other mail) which
confirms that the calls to ConvertTotBitmap and wxEmptyImage
are the main difference to GTKAgg.
The best would be to directly blit the Agg image
onto the wxFrame (however this assumes that these are
of the same type, which we don't know.
If not, the C++ route should be the fastest.
Unfortunately we both don't speak C++ and cannot
help further here).

Best,

Nikolai and Arnd
