MessageDecoder or CumulativeProtocolDecoder

Is there any performance tradeoff by using MessageDecoder instead of
CumulativeProtocolDecoder?

There's small additional overhead determining a proper MessageDecoder;
DemuxingProtocolCodecFactory iterates all registered MessageDecoders
to call decodable().

However, I don't think it's a big overhead because most messages can
be determined from its first few bytes.  Once a proper MessageDecoder
is chosen, there's no overhead.
