Hi, all,
In my test, when many different ARP request traffics are received from outline, 
OVS's kernel module will do upcall for these packets in order to find openflow 
rules.
Then ovs-vswitchd process will handle each packet and it's CPU cost may reach 
up to 100%, at a result, other control commands will be blocked and can't be 
handled.
So can we extract upcall handling work from ovs-vswitchd process as a single 
thread? Is there such plan for resolving this problems?

Thanks,
Jerry
