Could it be that the wsgiref is doing a reverse DNS lookup for every incoming call?
(for instance to determine the remote server hostname for some reason such as logging)
That could be a very slow operation.

Just an idea, I have no idea about the workings of wsgiref, I've just seen this 
happening in other situations.
