Proxying via HAProxy seem to slow down clear-text HTTP by 30%. That
seems *a lot* to me.

Are you offloading TLS at HAProxy and then forwarding the clear-text
bytes to backend ?
So the TLS numbers are actually measuring the difference in TLS
implementations ?

If you're not offloading TLS at HAProxy, then how come passing raw
bytes to the backend yields such a difference (lose 30% for clear-text
bytes, *gain* 100% for encrypted bytes) ?
