Hi Andre,

Quotation from uWSGI docs "Currently uWSGI async mode does not support the=
=20
read of POST data in async mode. This is not a big problem for most of the=
=20
apps, but if your webserver handler does not do buffering of the post data=
=20
(as apache) you could get some performance problem with big uploads."

May I suggest Nginx as a front-end with Django app served by gevent-fastcgi=
=20
via FastCGI.
