title: what parameters can impove kube-proxy performance?
body: <p>We are having problems on kube-proxy loading iptables. It locks docker when there's a large number of services. Is there a way to tune this with its parameters?</p>
  
  <p>From its documentation, I can only find --iptables-min-sync-period and --iptables-sync-period might be related? What's the recommended values for these in a large network?</p>
