How fast is it?

[pplonski]

Is there any speed comparison with nbconvert?

Is it possible to use execnb with an already running kernel?

I'm working on a tool for converting Jupyter Notebook to interactive Web Apps - to make notebooks accessible for non-technical users. The tool is called Mercury. You can add widgets to the notebook by simply adding a YAML header in the first cell. The framework is based on nbconvert. I would love to use a faster tool for executing notebooks.

The overhead is close to zero. So if you've doing a small amount of stuff in your kernel then the speedup will be dramatic.

If you give it a go, please let us know how you get along, and feel free to ask anything in issues here - at-mention me so I don't miss it.
