> We noticed a 4-5x increase in the worst-case P2P send latency (most notably
> sendReplication) in 1.12 vs 1.8. Further analysis showed that the increase in
> sendReplicationTime is related to how long it takes to create the sender
> connection. More specifically, all the time spent creating the sender is in
> the handshake. Experiments with various sleep durations in
> NioSslEngine.handshake() method showed that this issue can be fixed by
> replacing both sleeps handshake() method with Thread.yield() calls.
