Ssh – SMB SSH tunnel using putty client painfully slow

performanceserver-message-blocksshssh-tunnel

I've set up an SMB SSH tunnel using putty SSH client to edit my webpages directly from the server on my windows machine (also because my virtuazoo server doesn't allow NFS).

Even setting blowfish as encryption algorithm it goes ULTRA slow (2-3 KB/s)

Any ideas to improve performance?

The short answer is to simply give up on using SMB over a high-latency link.

The protocol preforms badly over high-latency links because it has many operations that require many round trips for acknowledgement. Tunning TCP over TCP also results in issues will work for both the SSH and the encapsulated protocol.

If you can get the client and server to support SMB2 there is some improvments. Or you might just want to switch over to sftp, webdav, or some other network protocol.
