i found it surprising that lua-cjson is significantly faster than
pbc-lua.  any theories about why?

json has no schema . Translate the tags need more time. and protocol buffer has default value for each field, 

pbc-lua need binding a metatable for each object. 

Encoding/decoding varint is more complex, and each protobuffer object need a varint for the length. the size of varint is not fixed. 

so encoding complex message need more memcpy or memmove.
