Please adjust network test for 80 Gbit bonded interfaces

Open devproof opened this issue 8 years ago • 2 comments

Please adjust network test for 80 Gbit bonded interfaces. It seems that the tests are optimized for 10 GBit interfaces. I was not able to verify 40 GBit or 80 GBit interfaces, because there seems to be a boundary at 10 GBit.

Can you explain more? Did you use -x option? That should run extra client per node creating the 2 TCP flows needed by bonded and even new teamed interfaces. That is limited to 20Gb for now. I will try to add option to pass integer to -x to specify bonding multiple, 2x, 4x, 8x.

New teamed interfaces in RHEL 7.x are supposed to provide full bandwidth for single TCP flow but that did not occur in my limited iperf testing of teamed interface. So I'm skeptical still about teamed interfaces.

Was not able to see more than 10Gb even using -x (multinic) option.
