Performance decrease in 0.5+

We are observing markedly slower data transfer speeds with the new Yggdrasil version.
To compare:

The tests were run using iperf3 over two laptops directly peering with each other over a WiFi connection.
How are they peered? (As in config/type of peering)
Which iperf flags?
Default iperf flags; peering was just running yggdrasil on two laptops connected over an ad hoc WLAN connection, auto-peered
Tried reproducing on Yggdrasil 0.5.5 over an Ethernet connection - no marked decrease observed. Closing.
