I'm using Azure ContainerApps with Dapr and I'm see very slow service invocation times under load

You can see in the picture that I'm making 7 parallel calls from my gateway ContainerApp to 7 different ContainerApps on the same ContainerAppEnv. Each parallel call only takes around 4ms to run (on the destination containerapp) but dapr takes over 100ms to make the round trip. The call is a post to a http rest endpoint.
This happens when the system is being load tested via azureloadtest with 5 virtual users only. It seems the dapr sidecars are running crazy slow compared to primary containers.The docs suggest that service invocation is super fast and considering the workload behind the rest endpoint, they shouldn't add much overhead.

Can anybody give some guidence? I'd really appreciate it.

Nick
