Re: speeding up FTP

["Larry \"DrFranken\" Bolhuis" <midrange@xxxxxxxxxxxx>]

Not necessarily in this order:

-Bigger buffers.
-Lower Latency.
-Faster connection.
-Bigger packets. e.g. Jumbo Packets. BUT These will not help if they 
can't get all the way between systems without getting fragmented.
-Sufficient system resources on both sides.

Also the higher the latency the bigger the buffers need to be and mostly 
it's the send buffer size on the source side.

Best I've done is Southfield (Detroit(ish)) to Grand Rapids on i 7.4 at 
a little over 6 Gbps. That was pretty good zip.  On that same network 
our Cybernetics devices managed 8Gbps but that's iSCSI not FTP.
