For my fellow geeks, has anyone else observed that WebDAV appears to be tremendously slower than SFTP when performing file transfers? I get the occasional odd WebDAV error as well when moving data to and from the server in question, and it borders on frustrating.
Anyone out there have a good recommendation for an SFTP/SCP implementation for Windows Server 2003? Leave them in the comments.

Here’s what I’m experienced. Without encryption acceleration hardware a Dell PE 2650 (dual-processor 2.8GHz Xeon, 4Gb memory) running Windows can perform SFTP transfers to/from a target sustained at no faster than 22Mb/s; I don’t know if SFTP is just inherently slower than IIS/Apache, but the bottleneck appears to be the processing power required to encrypt/decrypt the data. I believe that was using SSH.com’s SSH server, but similar results were seen with transferring data off the same system with pscp/psftp.
WebDAV increases the load even more, connecting to whatever backend system be it Subversion, etc.
