4315	slow copy performance when using LTFS as a destination	aletib		"Hi! 

I'm using MC v 4.8.24 on ubuntu 20.04
Built with GLib 2.63.3

I recently started using LTFS (a standard platform-independent feature that allows to mount LTO tapes as a file system) and noticed that when I'm copying from a local file system to a folder mapped to an LTFS-mounted tape, performance is very slow (about 20MB/s).
cp or any other copy system (of course copy same files from same source to same destination) have expected thorughput (+130MB/s).

The problem is not present if I use MC to copy from the folder mapped to the LTFS tape back to local drives so I assume this must be something related to the write process (or write speed measurement) that MC uses.

It would be cool to keep using MC for moving files to tapes especially for its selection interface.

Let me know if you'd like me to collect further info, thanks!"	enhancement	new	major	Future Releases	mc-core	master						no branch
