gatling-grpc's Issues
performance imporve
service resource have many rich.
Get the following data using Helloworld program which have not handle db/cache:
- Async: QPS < 2.5w
- Sync: QPS < 6k
- BUT use gatling test http, QPS > 5w

================================================================================throttle not work in gatling-grpc plugin
I write "setUp" like this, but throttle not work, the Running really produce 777 request, as expectation is reachRps*holdFor = 50 request. why? please answer my question, thank you.
setUp(scn.inject(atOnceUsers(777)))
.throttle(
reachRps(5) in (1 second),
holdFor(10 seconds)
)
.protocols(protocol)
support async？
run error
according to your readme, the follow errors:

Why have not import protobuf include file at simulation case file?
here use FundsRequest but not import me.macchiatow.gatling.grpc.FundsRequest. Thanks a lot!
maybe gatling-grpc should support response pass
example:
first grpc interface return {"num": 123, "name": "thinkerou"}, and second grpc interface will use before num result.
