Python applications sometimes need all the performance they can get. Think of e.g. web, REST or RPC servers. There are several ways to address this: scale up by using more processes, use Cython, use PyPy, rewrite parts in C, etc.

However, there are also quite a few things that can be done directly in Python. This talk goes through a number of examples and show cases how sticking to a few idioms can easily enhance the performance of your existing application without having to revert to more complex optimization strategies.
