Hello, I have developed a custom netdev provider and running OVS-1.10.0 in userspace mode. it works fine but the packet processing rate is quite slow. Packet transmission rate is about 500packets/sec but OVS is only able to forward 1/5th of this.
The arrival of incoming packet at the switch is indicated by a call back function, and this call back works fine for the actual packet transmission rate i.e. 500p/s. What I understand is the problem in use of poll_block() which is called in the main loop. Currently I use poll_immediate_wake to signal the polling thread to stop as soon as a packet is received in my call back function, however I see that multiple packets arrive before a single packet is received by the netdev-provider. Is this the best way to do this, or can signalling be done by any other way. I would appreciate if somebody can point me in the right direction. Thanks, -- *Junaid Zulfiqar*
