High CPU usage?

Traefik Traefik v2

Hi there,

We are using traefik as Kubernetes ingress controller, and I'm doing some test before upgrading traefik to v2.
I'm surprised by the high CPU usage, even without any traffic. With v1.7 it's less than 10m, and with v2.0 it's more than 100m per pod :thinking:
Before dropping an issue, is anyone facing the same behavior ?
