Special Forums Hardware Filesystems, Disks and Memory Slow copy (cp) performance when overwriting files Post 302831957 by rbatte1 on Friday 12th of July 2013 10:04:07 AM

I'm guessing that these filesystems are on the same local disk and therefore the IO overheads really mount up.

If you have a source directory src_dir and a target directory trg_dir you could try something like:-
Code:
cd src_dir
ls -1 | (cd trg_dir;xargs rm)
cp * trg_dir


Does that give you something to work from?
