Download performance query

by glangtry » Tue May 18, 2010 9:18 pm

We're using a licensed version of edtFTPnet/PRO and I'm running it on a x64 server running Windows 2008 Server. I'm downloading a 7MB zipped file using SFTP. I used the default TransferBufferSize and TransferNotifyInterval setting and it's taking about 19 secs to download the 7MB file. I changed the TransferBufferSize and TransferNotifyInterval to 65536 and the download reduced to 13 secs. However when I use the WinSCP client to connect using SFTP I can download the same file in about 5 seconds. When I set the TransferBufferSize and TransferNotifyInterval higher e.g. 131072 I get the error detailed below.

Is there any further settings I can modify to reduce the download time?
