Moving files in FTP

Why when moving from folder to folder on the FTP program collects data on the number and size of files. Easily transfer inside FATA may take up to several minutes, whereas in earlier versions it took seconds.

When delete - the same. As if skips each file to be deleted through my computer.

It's by design but it shouldn't be slower than before.

But it's just FTP, it's not my computer. Why do not just give a command to delete files from FTP, why do I have to wait as if SmartFTP delete / move files from my computer.
