gRPC C++ performance

[rajeev...@rediffmail.com]

Hi,

I am using gRPC c++ stack V1.0 on vxworks platform. It has been observed that Async Get call takes 3 mins to put the 11MB of data onto the wire. 

Is there any knob in gRPC stack to expedite this process?

Thanks

VxWorks is absolutely not in our list of supported platforms, and I am even surprised that the code managed to build and run there. 

With that kind of throughput, it sounds like you've got a bug somewhere in the core where it timeouts every now and then before processing more events. 

This sounds like a bug I've seen before. That being said, you're running a quite old version of grpc.

Had to do porting changes to make it work. Just to clarify that Async Get rpc is sending 11MB of data in one go 

::grpc::ServerAsyncResponseWriter < ::gnmi::GetResponse > responder_

::gnmi::GetResponse                                       reply_;  /11MB of data

                     responder_.Finish(reply_,Status(status_code, ""), this);
