> Flight benchmark program is using random test data as payload. Random data is hard to compress. Per my test, the compressed payload (zstd default level) is actually a bit larger than the original uncompressed payload. So compression is a pure loss in current benchmark.
> It's better to use real world test set for a more reasonable benchmark about how compression influences FlightRPC performance. Perhaps the benchmark (both client/server) could accept a path to an IPC file as an option.
