In my experience using nginx + gunicorn will help here is why: gunicorn create child processes for your server. This way you can have 3-4 process all working towards serving your web-application. Nginx helps for serving static files and reverse poxing to either flask / django process. You should also consider using something like supervisord. Supervisord will make sure you're processes are restarted if they crash for some reason.
