If the issue happens only when you use rsync the issue could be
different thing. To narrow down the issue, exclude any disk IOs
(e.g. rsync) and try benchmark re(4) with netperf.  Depending on
controller models, performance number may vary but you should be
able to get more than 700Mbps without TSO. With TSO, you may be
able to get 700-930Mbps.
If you still see the issue with netperf, show me the output of
dmesg(8) and 'ifconfig re0'.
