Not even that is the bottleneck.

I have no idea of how the notebook is implemented, but I think that's
really where the problem lies.  Probably that code is not written with a
large number of users (even non-simultaneous) in mind.  Because a
*second* notebook on the same physical server is much faster than the first.
