netty read part of the messages when the client write 1 command/ms ?

[Christian Migowski]

Hi,

this is called "packet fragmentation" and should be expected (i.e. it
is normal TCP behaviour and not a Netty bug). Trustin did write some
very good documentation about this in the Javadoc,
see here:

http://docs.jboss.org/netty/3.1/api/org/jboss/netty/handler/codec/frame/FrameDecoder.html

regards,
christian!
