ODL threads problem

Not that I care much for a paper but it would be good to have the CBench throughput test fixed soon so we can provide some good numbers to everybody.

Hi Luis,

It is a bad news for me that the bug is still there..Because my paper about testing ODL performance depends on ODL controller working properly. Anyway I will continue my paper even the bug is still there and even though the ODL controller's throughput is really poor, I have to finish my paper before deadline(15th this month) . 

 I really appreciate your kindly answer which help me a lot. Thanks :)

Best Regards!

Hi huagxufu,

Yes there is a couple of issues using CBench with OpenDaylight, just check the bottom of this wiki:


For the threads I do not really find any setting in OpenDaylight for this so I kind of assume it uses all available. I can ask next time I meet with OF plugin folks.

Hi Luis,

This two days I am busy with my paper. I am sorry for late reply. Thanks for your answer. So I am using a VM with 8 CPU Cores, then the ODL with be 8 threads listening Packet-in request ? is it right ? By the way, I think there is a bug in cbench throughput mode in ODL controller. Do you know is this bug fixed ? 

Best Regards !

Hi huangxufu, 

I am not sure we have a way to specify the number of threads but i will look at it tomorrow. By default controller uses all available CPU Cores or threads in a multi thread processor.

Hi Luis:

Sorry for disturbing you :)
Do you know how to configure the threads of listening Packets-in request just as floodlight using following command:net.floodlightcontroller.core.internal.FloodlightProvider.workerthreads=X in /floodlight/src/main/resources/floodlightdefault.properties file  or nox with :./nox_core -i ptcp:6633 switch -t x .  Or currently we can’t configure it ? so how many threads are listening the packet-in request if just as default ? Thank you for kind help , I really need to know to write a paper.

Best Regards !
