Either your local workstation or your server might not be able to encrypt file transfer stream at the same speed, your connection is able to transfer it. You may try to choose different encryption algorithm on Login dialog. Blowfish is usually a lot faster than AES. Also SSH-1 is in general less CPU intensive than SSH-2. SCP protocol is usually faster than SFTP too. On 11/28/05, lin q wrote: > Hi, > I have 2 Windows XP machines installed with latest cygwin.
