OK, I think I have figured it out and I'll add it here in case it saves someone from being as mystified as me:
Chrome sometimes uses multiple http connections. dev_appserver only uses a single connection. If you use chrome to access your development server you will very likely end up with it intermittently hanging, timing out or just responding really slowly. The quick fix: don't use chrome on the development server. link to a source discussing the issue: https://groups.google.com/group/google-appengine-python/browse_thread/thread/619d46a1e3d08c67 Best, Alex.
