I created a Dockerfile to revert commt b19c81 in protobuf and build the wheel file for python 3.11. It is faster than the python backend, also use far less memory: for 2GB of input python backend used another 3GB memory, upb used almost no extra memory . This can be add to the multi-stage dockerfile @nkemnitz suggested in #406
