Hello, I noticed that the ipvs-b process is tending towards 100% CPU utilization on some of my IPVS LB clusters. It seems process is limited to one core with our version of Centos7 (kernel 3.10.0-957). This would seem to put a practical limit on the number of sessions that can be handled even when network throughput is well below capacity. We've seen some recent increases in our connection counts and have started seeing some dropped packets on the VIPs.
Has there been any changes in recent kernels to make this not be limited to a single core and to be able to handle a higher number of synced sessions? Some context for the question. We have 8 linux servers in each cluster using keepalived to setup ip_vs. All nodes are active running both the master and backup sync processes (-a and -b). We use BGP to route traffic to the nodes.
