The Performance Drama of SQL Ocami

Coming from a Java background I didn't pay too much attention to the way our code was written might be slower or faster. With Python it's mostly C Python so there's this big gap where if you do something in a for loop it might be very slow and you do the exact same thing with like the zip call it's a million times faster because the zip calls are written in C. The most recent incarnation of that has been more performance improvements in version 1.0 but also a lot of a lot of new documentation  that refers specifically to the notion of performance.
