when i run the iperf3 i see the following

iperf3 -c 192.168.3.10 -t 10000 -P 4

[  5]   1.00-2.00   sec  29.9 MBytes   251 Mbits/sec    0    306 KBytes
[  7]   1.00-2.00   sec  29.3 MBytes   246 Mbits/sec    0    376 KBytes
[  9]   1.00-2.00   sec  29.3 MBytes   246 Mbits/sec    0    306 KBytes
[ 11]   1.00-2.00   sec  29.4 MBytes   247 Mbits/sec    0    262 KBytes
[SUM]   1.00-2.00   sec   118 MBytes   988 Mbits/sec    0

both hosts are in the same l2 segment

I expect a total speed of 3000 mb.
