I can somewhat help out there ...

I've tested that Visual module. It's somewhat more geared towards the Visual 
3.x API, it's *quite* a bit slower than visual, and it's not as feature rich. 
Also there are some draw backs due to bugs/limitations in the traits 
implementation limiting the range of usable sizes, etc. Some code also has to 
be (slightly) adapted to fit that visual API of Mayavi.

Performance can be somewhat boosted significantly by switching to the Qt4 
backend over the default wx windowing backend. Still, performance is not 
nearly as good as with Visual Python.

I did a presentation with a paper at the last Kiwi PyCon touching this topic. 
The slides are here:

extravaganza

A paper of that is soon to be published under the Python Papers Monograph 
Series for that: http://pythonpapers.org
