Hi, I have the same issue here. When I use SFTP (WinSCP) to transfer from my Windows XP SP2 box to my local server, I can only utilize about 1/10'th of the bandwith (100mbit). On the other hand, when I use FTP or SMB to transfer files, I can utilize the maximum bandwith.
On both boxes, the "symptoms" are the same: - Lots of available CPU time - No significant disk I/O - Quite a lot of available RAM.
