udp packet processing is done in a single go-routine (seperate go routine per k8s udp service).
For scenarios like DNS, this can get slow.

(This performance issue has been fixed with the iptables proxier.)

Parallelizing the udp packet processing can be done for 1.1 (3-4 hours of work), but seems a bit risky given that we are close to 1.1 release.

This work can be done post 1.1, IF, iptables-proxier is still not the default in release 1.2
