I selected SageMath. Is that sagenb?

So David is running the Jupyter notebook, not sagenb. The Jupyter notebook comes with the Sage Jupyter kernel which is mostly just the normal IPython kernel plus the usual Sage pre-parsing stuff and a few other bells and whistles. No idea why it would be abnormally slow, except again for the Windows Firewall idea. I need to install a Windows 7 VM so I can test more on there, as I've only tested on Windows 10. But as far as Cygwin goes I don't think there's an enormous difference between running on Windows 7 or 10. > Thanks again. > > > > >> > >> > >> Sometimes the first command takes a little longer than most as there's > >> some startup overhead, but a second is on the long side.
