I dimly remember a HZ setting, maybe kernel config option?
 From years ago. I can't find it in recent /sys/amd64/conf/*
Does this functionality still exist or has it moved elsewhere?
Or did it ever exist?

I am seeing slow network throughput speeds in virtio-net relative to linux vms
on the same host and thought maybe it had something to do with polling too fast.
