Slow using WinSCP.com vs WinSCP GUI

Hi,

When transferring a 10GB file using the GUI in Explorer mode to a local drive, transfer rate is 20MB/s.

The same action executed through the console on the same machine (A) gets 250kB/s transfer rate.

The same action executed through the console on different machine (B) on same network gets 20MB/s transfer rate.

Only difference between A and B is free space on C: drive: A has 8GB free, B has 30GB free. Same internet connection, same files, same everything else. I am using the latest version of WinSCP on both machines (5.17.9). This leads me to believe that somehow during the console transfer the file is temporarily cached on the C: drive, whereas not during Explorer GUI copy by "dragging the file" from source to destination? I have tried many console switches and options but nothing makes a difference. Can you help?

Thanks,
Matthew

Please attach log files from both GUI and the script.

Martin,
Appreciate the quick reply. Seems disabling logging allows the console script to run at the same speed as the GUI. I had ruled this out as I have 2 log files, both saved to the same shared drive. However I will investigate further and respond if I can't get to the bottom of it.

Kind Regards, Matthew
