   The "bandwidth-delay product window limiting" code in 5.x appears to be
quite broken. In my tests here, the window is hard limited to 2 segments,
regardless of the actual bandwidth-delay product, and this results in very
poor performance over non-local TCP connections.  I'd suggest shipping 5.4
and future releases with net.inet.tcp.inflight.enable=0 until this problem
can be fixed.
