The performance impact of a middleware depends almost completely on
what a given middleware does. If I am not mistaken adding a middleware
that does nothing gives you just one function call per the
middleware's functions (process_request, process_view, ...) when
processing a request. If you do not have insane amounts of middlewares
defined then there should be no performance problems.

However, if you do something complex in the middleware then
performance will of course be affected.

In general I have a feeling that Django is still fast enough, and the
added features outweigh the performance penalty.
