Thanks for your advice. Add '-lro' and '-tso' to ifconfig,
transfer rate up to almost native NIC speed:
# dd if=/dev/zero of=/.dake/tmp/foo.img bs=1k count=1m
1048576+0 records in
1048576+0 records out
1073741824 bytes transferred in 10.688162 secs (100460852 bytes/sec)
#
BTW in VM on behyve, transfer rate to NFS mount of VM server
(bhyve) is appreciably low level:
# dd if=/dev/zero of=/.dake/tmp/foo.img bs=1k count=1m
1048576+0 records in
1048576+0 records out
1073741824 bytes transferred in 32.094448 secs (33455687 bytes/sec)
