1) Try to add to the config /boot/loader.conf :
net.isr.defaultqlimit=2048
net.isr.maxqlimit=40960
2) Try to add to the config /etc/sysctl.conf :
net.inet.tcp.recvbuf_inc=524288
net.inet.tcp.recvbuf_max=16777216
net.inet.tcp.sendbuf_inc=524288
net.inet.tcp.sendbuf_max=16777216
net.inet.tcp.sendspace=65536
3) On the network card turn off TSO, rxcsum and txcsum
ifconfig ix0 -rxcsum -tso -txcsum lro
