SSH-2 window management has also been revised to reduce round trip delays during any large-volume data transfer (including port forwardings as well as SFTP/SCP) Doing a quick test, I'm seeing that PuTTY 0.61 speeds up SFTP downloads of already compressed data by a factor of 4 compared to PuTTY 0.60. Fantastic!
