Hello gRPC group, I'm working in Applied Materials SW team, and we're checking the possibility of replacing our RPC based CORBA with gRPC. My benchmark includes comparing gRPC vs CORBA performance while sending various message sizes from client to server. The server replays immediately for each call. Both client and server are C++ based, and I'm using windows. I noticed that for small messages one RPC time is about ~20 ms between the two computers (from the client call until it gets response). But from a certain message size the call time jump to ~220 ms. I see this 200ms overhead from above ~9500 bytes during connection, and with message size over ~1070 when I just start connection. When performing many gRPC calls this 200ms overhead become a problem. Please see the following graph which represents call time vs message byte size.
[cid:[email protected]] When using CORBA (which is also based TPC) I don't see such overhead, a call takes ~15ms. Are you familiar with such behavior? Can you explain it? Thanks Meir Vengrover, SW engineer, Applied Materials. -- You received this message because you are subscribed to the Google Groups "grpc.io" group.
