362Mb/s is way too low for 1GbE.
You might want to try a UDP test to isolate the bottleneck somewhat.
Try netperf -tUDP_STREAM -Hmacpro02-m -- -m 1472

Iperf is probably your problem, it tends to perform really poorly on
nearly any OS other than

You might want to try setting:
net.inet.tcp.inflight.enable=0
Just changing this on our FreeBSD 6.2 boxes enabled them to achieve
