This patch reorders the masks array every 4 seconds based on their usage count. This greatly reduces the masks per packet hit, and hence the overall performance. Especially in the OVS/OVN case for OpenShift. Here are some results from the OVS/OVN OpenShift test, which use 8 pods, each pod having 512 uperf connections, each connection sends a 64-byte request and gets a 1024-byte response (TCP). All uperf clients are on 1 worker node while all uperf servers are on the other worker node. Kernel without this patch : 7.71 Gbps Kernel with this patch applied: 14.52 Gbps We also run some tests to verify the rebalance activity does not lower the flow insertion rate, which does not.
