First, are you using: option optimize_for = SPEED; ? If not, add that line to your .proto file. But even without that option, the speed shouldn't be that slow. Maybe you can run in a profiler to see what's taking so long?
Are you writing to an in-memory buffer or some sort of output stream? Is it possible that the stream is blocking? For reference, most of my C++ serialization benchmarks get around 250-500 MB/s with optimize_for = SPEED and 15-25 MB/s without it.
