another observation - outbound Spin to Azure/HTTP resource response times are quite high (Dapr shared)

│ Receiver body {"data":{"orderId":2,"delivery":"Express"},"operation":"creat │
│ outbox response: 200 elapsed: 54.02ms                                       │
│ Receiver body {"data":{"orderId":2,"delivery":"Express"},"operation":"creat │
│ outbox response: 200 elapsed: 17.88ms                                       │
│ Receiver body {"data":{"orderId":2,"delivery":"Express"},"operation":"creat │
│ outbox response: 200 elapsed: 13.45ms

with Dapr sidecar roundtrip times are lower

│ Receiver body {"data":{"orderId":2,"delivery":"Express"},"operation":"creat │
│ outbox response: 200 elapsed: 10.85ms                                       │
│ Receiver body {"data":{"orderId":2,"delivery":"Express"},"operation":"creat │
│ outbox response: 200 elapsed: 8.73ms                                        │
│ Receiver body {"data":{"orderId":2,"delivery":"Express"},"operation":"creat │
│ outbox response: 200 elapsed: 8.36ms

comparing with dependencies duration ex Dapr sidecar

  1. one can see the for Dapr shared ~6ms are lost between app and Dapr, with Dapr sidecar ~1ms is lost
  2. substantial latency is on the Dapr to resource roundtrip
