Re: FTP performance

[Philipp Rusch <Philipp.Rusch@xxxxxxxxxxxx>]

Hi Patrick and Theresa,

the problem with *FULL for duplexing mode is that you loose capability
to handle errors on the hardware layer. You can even get into the
funny situation that a 100 MBit Ethernet line *FULL can be slower than
a 10 MBit line (because of the repetition needed on the higher layers)!
General rule of thumb is to start with *HALF connections and see what
 happens ...
