It seems the problem is that you don't specify mtu adding
mtu 3100 fixed for me.

The MTU setting is extremely strange.

When I left it at the default value, the ingress was limited to a sustained
rate of about 100 kbit/sec.

When I set the MTU to 3100 as you suggested, the ingress had a sustained
rate about 6 mbit/sec which is better but still not the target I wanted.

When I set the MTU to 5k, the ingress has a sustained rate about 2.6
mbit/sec
which I find counter-intuitive since it does not seem to be a linear
relationship.

Does anyone have any insights into this?

There is some info in the police.txt there, it's old and I don't know how valid it is.

I've never used/tested policers with anything but the simplest of params.

I've also never tested any tc on virtual setups.
