As for Total commander example, that was out of the box experience, without any tweaks. I just wanted to point out that even when using emulation layer to access Windows native filesystem type, Linux was significantly faster on file system operations. As for my homework "copy" command, I know that it is not fully replacement to file copy windows command, but if copy operations takes >10min, all those checks and additional tasks shouldn't make IO bound operation take couple time longer than what some student implemented as homework.
