[Sorry if this shows up as a dupe]
We've tried this on several PCs running XP and 2K with identical results. Running the latest (988?) build of SmartFTP.
We regularly upload to a site about 16 hops and 40-50 ms away, with an OC3 on each end.
Using the Windows command line client, we see speeds of 15M+ bits/sec, roughly the same as we get from linux, Mac and Irix c/l clients.
But SmartFTP never exceeds about 1/10 of that, around 1.6Mb/s.
We've applied all sorts of TCP registry tweaks, etc with no change.
I suspect that SmartFTP is ignoring the available TCP window size and using its own value that is too small for this fast connection.
Is there any way to change that, or at least to diagnose this further?
Thanks for any advice.
