Hello,
I'm e-mailing this list as recommended by Justin in the OpenFlow mailing
lists.
So i would like to ask now more specifically about the CPU usage of the
OpenVSwitch and the different types of packet size in a flow.
My test setup consists of 3 PCs, where 1 sends data to 3 by
2(OpenVSwitch,Nox). The traffic was generated by Iperf UDP.
I tested with datagram sizes of 100 bytes and 1470 bytes, and the
difference i've noticed is that in the CPU monitor, when i use a 50Mb/s
bandwidth and 100 bytes of datagram, the CPU usage meter rises up and
stays high for a few seconds, and then drops and becomes "normal", even
with the flow passing through it.
With the same BW and 1470 byte-datagram, the CPU usage meter didn't rise
much, and as the other one in a few seconds you just could say its there...
Is this normal?
I was trying to measure how much CPU the OpenVSwitch is consuming for
each type of flow, do you guys think its possible?
Millions of Thanks!!
Peace!
Victor T.
