Ben, 2M result I mentioned is probably not very accurate (but real) - it's 500k rows query with single numerical field, and parseInt(buffer.toString()) seems to be much slower than manual int parsing ( https://github.com/sidorares/node-mysql2/blob/master/lib/packets/packet.js#L183 ) Here is simple benchmark manual vs builtin parseInt from buffer: https://gist.github.com/sidorares/5612620 - there is 10x times difference.
Inner loop row parser is compiled dynamically based on field types - https://github.com/sidorares/node-mysql2/blob/master/lib/compile_text_parser.js Removing Function.bind() also helped to save 10-20% couple of times. De-framer stream to packets does not buffer incoming data and in most cases executes parser on incoming chunk without copying.
