Hello everyone,

I want to start using WinSCP for moving files from my server to my home computer, however when I do I have very slow D/L speeds like < 1 Mb/s (single file transfer). When I use CuteFTP I get 25-30 Mb/s (again single file transfer not split into parts).

Can someone help me start to trouble shoot why I get slow speeds with WinSCP?

Thanks

Please attach a full log file showing the problem (using the latest version of WinSCP).

To generate log file, enable logging, log in to your server and do the operation and only the operation that causes the error. Submit the log with your post as an attachment. Note that passwords and passphrases not stored in the log. You may want to remove other data you consider sensitive though, such as host names, IP addresses, account names or file names (unless they are relevant to the problem). If you do not want to post the log publicly, you may email it to me. You will find my address (if you log in) in my forum profile. Please include link back to this topic in your email. Also note in this topic that you have emailed the log.

Thanks for the help. Should I choose Normal, Debug1, or Debug 2 level of logging?

Thanks for the help. I choose normal mode and when I chose debug 1 or 2 things really slowed down and I didn't get a normal log file. I tried to remove any information that I thought would be bad to post openly (passwords, usernames, etc.) I noticed that I am using compression when transferring the files and maybe that isn't needed if the files are encrypted? Maybe that is a lot of work for the server or my computer?

Thanks

Thanks for your report. Can you email me a Debug 1 log file anyway? Ideally for a single file mid-sized file only. Turn off compressions to rule it out.

Hi

I have same problem and it is same with older, default and newest version. I also get decent speeds using other SFTP programs but with WinSCP download speed is one tenth of the upload speed from/to my SFTP server...
