Typhoon publishes expected pod-to-pod network performance details. A Typhoon AWS v1.11.2 cluster with Calico v3.1.3 nearly saturates the link with pod-to-pod bandwidth of ~980MB/s (range 950-1000MB/s) when using an 8981 MTU on a suitable instance. Testing Calico v3.2.0, with both MTU 1480 and 8981 shows only 400-500MB/s.

This update is on hold.

This was totally unrelated to Calico itself. A stray colon in value:From (now corrected to valueFrom) in the Calico Daemonset in poseidon/terraform-render-bootstrap#74 meant the IPIP MTU was left empty. Performance on Google Cloud was as good as expected (bc the default is 1440), whereas AWS needs a custom MTU for best results. The typo has been corrected and performance matches expectations.
