Hi, I'm studying OVN these days. I found that ovn-controller issue too match flow table to br-int in compute node. Number of flows it too large。
The question is that those flow tables may reduce efficiency of flow match in packet forwarding. I have heard that efficiency reduce heavily when number of flows more than 20000 in kernal. Has any one make stress testing of packet forwarding in ovn environment, especially several vms on one hypervisor. Thanks for any advice. Wilence Yao
