By far the best FTP server going today. It is also underpriced. [Don't
tell the developer :)] I have had some problems getting the external .dll
working with Emerald, but it still is excellent. It now supports
multi-homed IP addressing, and from personal test has the highest
performance benchmark. The transfer rates were 5-10% faster than WAR-FTP
in the same testing and 8-13% faster than IIS. The only hard part is
getting the order in and processed. Took less than 36 hours.... :)
