[gentoo-user] [OT] how to delete a directory tree really fast

[Helmut Jarausch]

Hi,

Is there anything faster than
rm -rf <TREE>

?

I'm using rync with the --link-dest=<PREVBackUp> option.

Since this option uses hard links extensively, both, <TREE> and  
<PREVBackUp> have to be
on the same file system. Therefore, just re-making the file system  
anew, cannot be used.

There are more than 55,000 files on some <PREVBackUp> which is located  
on a BTRFS file system.
Standard 'rm -rf' is really slow.

Is there anything I can do about this?

Many thanks for a hint,
Helmut
