Hi Elliot,

Thanks for the reply.

What was your setup that allowed you to reach 500Mbit? How were you 
copying the files? Were you using SFTP, SCP or rsync?

Was it a Cygwin to Cygwin transfer, or was there another OS involved?

Sorry for all the questions, I am just trying to rule out all possible 
variables.

Cheers,

Jordan Geoghegan
