I am getting a file transfer (upload) speed of about 400KiB/s to our Fortress server, using WinSCP. By comparison we had about 2000KiB/s on our other SFTP server running under an old version of COPSSH.  Fortress is installed on a physical Windows Server 2012 machine.

Are there any tweaks or registry settings you can recommend for improving the file transfer speed?

Thanks,
Robin
