Thanks Matt!
I've been testing this for a couple weeks (in various forms). I've
been getting over 96% reduction in block-bytes sent. I don't have a
good metric for it, but bandwidth spikes are greatly reduced. The
largest blocktxn message I've seen on a node that has been up for at
least a day is 475736 bytes. 94% of the blocks less than 100kb must be
sent in total.
In the opportunistic mode my measurements are showing 73% of blocks
transferred with 0.5 RTT even without prediction, 87% if up to 4
additional transactions are predicted, and 91% for 30 transactions (my
rough estimate for the 10k maximum prediction suggested in the BIP.
