Hi @all,
I have a gRPC application with the following setup:
- bidirectional streaming
- synchronous gRPC server in C++
- gRPC client in go
The server is running in an environment with 2 CPUs:
I have run my application once with NUM_CQS equals to 1 and the second time
with NUM_CQS equals 2:
builder.SetSyncServerOption(ServerBuilder::SyncServerOption::NUM_CQS, 2);
builder.SetSyncServerOption(ServerBuilder::SyncServerOption::MIN_POLLERS,
1);
builder.SetSyncServerOption(ServerBuilder::SyncServerOption::MAX_POLLERS,
1);
builder.SetSyncServerOption(ServerBuilder::SyncServerOption::CQ_TIMEOUT_MSEC,
1000000000);
For the same number of clients making gRPC requests in parallel, there is
no difference in throughput for the two runs. Although I would expect that
with setting 2, we would have higher throughput.
Is my expectation wrong? How can I control how many cores are used by the
synchronous gRPC server?
Thank for inputs!
