A couple of months ago I asked on IRC how to properly switch from 
version 1 to version 2 of the space cache. I also asked if the space 
cache v2 was considered stable.
I only remember what we talked about, and from what I understood it was 
not as easy to switch as the wiki may seem to indicate.

We run a box with a btrfs filesystem at 19TB, 9 disks, 11 subvolumes 
that contains about 6.5 million files (and this number is growing).

The filesystem has always been mounted with just the default options.

Performance is slow, and it improved when I moved the bulk of the files 
to various subvolumes for some reason. The wiki states that performance 
on very large filesystems (what is considered large?) may degrade 

I would like to try v2 of the space cache to see if that improves speed 
a bit.

So is space cache v2 safe to use?!
How do I make the switch properly?
