Just want to point to some excellent material that was recently presented at
the course Advanced Scientific Programming in
Python<https://python.g-node.org/wiki/>at St Andrews. Day 3 was titled
"The Quest for Speed" (see
https://python.g-node.org/wiki/schedule) and might interest you as well.

Regards,
David
