> the issue with gRPC Java is that it has a fixed, small buffer it uses for backpressure, so effectively every write will trigger backpressure and artificially throttle the producer, regardless of actual network conditions. This has been known for years but the upstream is not interested in fixing it: https://github.com/grpc/grpc-java/issues/5433 yes, we also found the same issue and tried without backpressure, but still no changes in performance(not in the benchmark, nor in real code). -- This is an automated message from the Apache Git Service.
