Hello Larry,

Not necessarily in this order:

-Bigger buffers.

This helps the most!

-Lower Latency.
-Faster connection.

Nothing one can easily set via OS parameters. ;-)

Allow me to add "negligible packet loss".

-Bigger packets. e.g. Jumbo Packets. BUT These will not help if they can't get all the way between systems without getting fragmented.

(L2-)Switches don't fragment. Only routers (or L3-Switches doing routing) do. You usually can't get more than 1500 Bytes across the internet.

-Sufficient system resources on both sides.

Isn't it safe to generally assume this is given with todays systems? (FTP binary transfers easily push a 150's CPU to 100%, and the 10M 2713 isn't even the limit. ;-) )

On that same network our Cybernetics devices managed 8Gbps but that's iSCSI not FTP.

FTP is a protocol for transferring bulk data as fast as possible, in one stream. No chopping and matching storage blocks and network packets needed. Nothing can beat FTP in terms of sheer speed. :-) But it's not particularly firewall-friendly, and usually unencrypted. Thus my choice for LAN transfers. :-)

:wq! PoC
