title: Does HTTP/2 need to be implemented end-to-end to be useful?
body: <p>How much of the performance benefit of HTTP/2 is lost if only the client &lt;-> load balancer is HTTP/2 and the actual web server isn't? I'm guessing it depends on the latency and bandwidth between the load balancer and the server, but if you had to guesstimate for the average case, would it matter at all?</p>
