Do the timing in the generator itself, or use middleware, something like
```python
class TimingServerMiddleware(flight.ServerMiddleware):
def __init__(self, start):
self.start = start
def call_completed(self, exception):
print("Duration:", time.monotonic() - self.start)
class TimingServerMiddlewareFactory(flight.ServerMiddlewareFactory):
def start_call(self, info, headers):
return TimingServerMiddleware(time.monotonic())
server = Server(..., middlware={"timing": TimingServerMiddlewareFactory()})
```
