> Reporter: Nico Kruber
> Assignee: Nico Kruber
> Priority: Minor
>
> {{NettyMessage}} may be improved slightly performance-wise in these regards:
> - in {{NettyMessage.NettyMessageDecoder#decode()}}: instead of having
> multiple if-elseif-... use a switch to cycle through the message ID
> - use a static {{NettyMessage}} subtype {{readFrom(ByteBuf buffer)}} - we do
> not really need to have a virtual function here
