Why does HTTP2 help with this? Load balancers use one keepalive connection per request and don't experience head of line blocking. And they have slow start disabled. So even if the latency of the final request is high, why would HTTP2 improve the situation?

If every request is quick, you can easily re-use connections, file handles, threads, etc. If requests are slow, you will often need to spin up new connections, as you don't want to wait for the response that might take hundreds of milliseconds.

But I did start by saying it's not important. It's a small difference, unless you hit a connection limit.
