I'm using WinSCP 5.8.3 RC3 (Build 6701)

Upload speed of site.zip (45mb) using WinSCP -> 30kb/s
Upload speed of site.zip (45mb) using Filezilla -> 680kb/s

Both are using FTP connections, No Ecryption mode.

Please attach a full log file from both clients.

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 can mark the attachment as private.

Thanks for the logs. Can you enable TLS in WinSCP to make the sessions identical? I do not expect this to fix the problem, but I just want to remove any differences before starting the investigation. Post new logs then.

When you select the FTP protocol, you get Encryption box on the right. Select "TLS/SSL explicit encryption" there.

Allright, I'm using this setting, and I can confirm Filezilla works 10x faster than WinSCP. We can Teamviewer so you can see it yourself if you wish.

01-06 at CPU tab in task manager.
And I test today speed - the result is:
Filezilla - stable 10.4-10.8 Mib.
WinSCP - 4000KB - 10000KB. (Not stable upload speed)
Win7 64Bit. File is 2GB.
Script is:
Code:
open sftp://Login:Pass@ftp.blah-blah.lv:2223 -hostkey=*
option confirm off
option transfer binary
put -resumesupport=off test.test
exit
