Hi,
I'm seeing very slow (or time outs, depending on the client) for
requests made over HTTP 1.1. If I force curl to use HTTP 1.0,
everything works quickly.
The behavior is consistent over curl or when using Rainbows behind Varnish.
Any ideas?

Your app is missing the Rack::ContentLength (and Rack::Chunked)
middlewares. This is mentioned at the bottom of the manpage[1],
but I suspect it might be necessary to add a FAQ entry.
