winscp extremely slow when you copy files from one dir to another dir on one server

I have directory A, which contain subdirectory B and 1000 files.
I select all files, and move them to directory A.
Operation take around 5 minutes.
If I do it from linux command prompt, it take less than one second.

I mean, I move files to directory B

That's not unexpected.
If you do mv on a shell command-line, everything happens on the server.
But if you move files using a local client, there's a roundtrip for every file, what causes a significant delay.

why not use command line client for such operations, something like
mv file1 ./another_dir/ && mv file2 ./another_dir && ...

I'm not sure now, if this was posted by the same or different user. So I do not know whether this is a question (regarding a possible implementation) or a suggestion to the original poster.
