I was somewhat surprised to see that the django.core.cache module didn't support an mmap based cache. The default cache is per-process, so it's somewhat limited in effectiveness. Something like Redis solves that, but adds another running process to manage. In the PHP world, for example, acpu is a popular user-facing cache that uses mmap so that it works cross-process, then you can move to redis if you want to scale across more than one host.
