The limitation is not my hardware. The servers are both Dell R900 with SAS disk arrays. Also, from a Windows virtual machine, inside the same server, I get around 400 MB speed using FTP transfer, windows to windows. There must be a different way to do this from Linux.The files are sparse files, and I need to keep them that way, that's why I use rsync.
