Network policy slows down traffic with canal

[agvsap1]

Hi

I have Rancher v2.5 cluster deployed in IaaS enviroment with 2 workers servers. My appls are workinf fine, but when I apply my networkpolicy to control the traffic between namespaces, the access to my application from outside my cluster is slow.

My networkpoliy slows down traffic to access my applications.

I have network pluging "Canal", is a project that combines Flannel and [Calico] for CNI Networking. It uses Flannel for networking pod traffic between hosts via VXLAN and Calico for network policy enforcement and pod to pod traffic.

This is the log from my canal pod:
