FWIW, the python protobuf library defaults to using the C++ implementation with bindings. So even if this is a blog post about implementing protobuf in C, it can also help implementations in other languages.

But yes, once you want real high performance, protobuf will disappoint you when you benchmark and find it responsible for all the CPU use. What are the options to reduce parsing overhead? flatbuffers? xdr?
