Hi,
Did anyone here used gRPC to implement low latency distributed stuff?

What is the performance of gRPC when there is a need to finish RPC calls 
within 2 ms between a server and client for every RPC call? Can gRPC do 
this for 99 percentile of traffic at say 50000 RPC calls per second?

Does anyone have any experience with such a system yet?

Yes, I benchmarked and it is order of magnitudes slower compared to writing 
a custom messaging bus over zmq. Am I doing it wrong?
With custom zmq messaging bus we get latency in order of microseconds 
between 2 services on same host (21 us avg) vs 2 ms avg for gRPC. 

That is extremely slow compared to zmq., i.e x1000 time slow.

How can I fix this?

Thanks,
