Slow SFTP Download Speed (Upload Speed is Fine)

Thank you very much for your reply.

I already tried turning off both, but that didn't change anything.

That doesn't make any difference. I also tried dragging and dropping from one program to the other one, which lead to a normal download in the target program - fast in Explorer and slow in Directory Opus.

I didn't observe anything of interest when displaying the processes of all users in the Task Manager (sorted by CPU usage).

Any other ideas?

Cheers,
Jan
