Version of traefik bundled with colima is sluggish with high latency

[torenware]

Describe the Issue

Using the bundled traefik ingress controller, paths routed via ingress resources are very slow, taking several seconds to process, even if done immediately after another request. This appears to be an issue from traefik's issue queue which has been fixed since the version bundled by Rancher.

To Reproduce

Steps to reproduce the behavior:

1. colima start -e
2. Make sure k8s and ingress are true, to install ingress.
3. Modify the supplied manifest (slow-ingress-controller-yaml.txt ), and alias 127.0.0.1 in /etc/hosts to match the ingress definition.
4. Create a deployment, service and ingress resource from the edited manifest.
5. Go to the aliased host name from the manifest. Check how long it takes for a response.
6. Do a hard reload in the browser, to see how long it takes.
7. If you observe the issue, first response will take a few seconds, but so will subsequent tries. Response time does not improve.

Expected behavior

Response time will be fast, even if there is some latency on the initial pull of the URI.

Additional context

At the suggestion of the Traefik developers, I modified /var/lib/rancher/k3s/server/manifests/ingress.yaml to use the latest docker image of the traefik ingress controller. This worked.
