sftp upload very slow to some servers application (General questions)

We have a visual basic 6 application that is using wod's sftp library to send files to sftp servers. Some servers like it - ubuntu. Others seem to take a very long time (transfer rate < 1 meg per minute) and others time out after about 60 minutes for one client. Any ideas on what I'm doing wrong? Are there different encryption algorithms in the land of sftp that I am struggling with? Is there some way I can find out why this is happening?
Thanks,
Steve

Steve,

What exctly does slow mean? Can you give me time estimate, and file size?

How long does it take using some other client?

Also, what version are you using?

Thanks for getting back to me. I am transferring a 2 megabyte file and it is taking over 4 minutes. I am using wodSFTP.dll version 2.2.2.12
The slow transfer is to a windows 2003 server running ssh tectia as the sftp server

Transferring the same file to a ubuntu over the same network it takes < 5 seconds.
Any ideas.
Thanks
Steve

Steve,

You are using very old (4 years old) version of wodSFTP.

If you didn't extend your subscription for wodSFTP can you maybe test with latest DEMO version from our website?

Before you do that please backup somewhere you old licensed version.

Let us know how it goes.
