Help with using nttcp to measure network speed

[Thaidog]

The following are two tests... one before mtu set to 1500 and the after test set to 9000:


[tylerm@mercury ~]$ nttcp -T 10.0.1.21
Bytes Real s CPU s Real-MBit/s CPU-MBit/s Calls Real-C/s CPU-C/s
l 8388608 0.61 0.01 109.7384 7457.3690 2048 3348.95 227580.8
1 8388608 0.71 0.02 94.0623 2918.1573 5795 8122.49 251989.4

[tylerm@mercury ~]$ nttcp -T 10.0.1.21
Bytes Real s CPU s Real-MBit/s CPU-MBit/s Calls Real-C/s CPU-C/s
l 8388608 0.39 0.01 172.1142 7457.3690 2048 5252.51 227580.8
1 8388608 0.71 0.02 94.1065 2684.6767 5798 8130.51 231947.8

Looks like the performance got better with Real-MBts/s but maybe I'm reading this wrong?
