The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.
If you know of an easy to use, open source, search engine ... please contact support@midrange.com.
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.

What are the optimal parms for speeding up FTP?
Thinking buffer size would be a factor.
Our settings are:
TCP receive buffer size . . . . 2097152 512-8388608, *SAME, *DFT
TCP send buffer size . . . . . . 2097152 512-8388608, *SAME, *DFT
Other settings?
Thx,
Jerry
