1. Convert to a 16k or 32k leafsize.
2. defragment (each non-trivial file) every now and again [eg. find / -size +16k
-type f -exec btrfs filesystem defragment -vf '{}' ';' ]
3. Note that btrfs in kernel 3.6 (vs 3.5) does appear to be quite a bit quicker.
I'm running Siduction kernels whilst Debian is on freeze at 3.2. I found 3.5
really quite awful - not sure why.
Make sure you discount other factors.
I'm not sure defrag goes so far as to consolidate files by moving bits out of
the way yet, so you may find that the number of fragments in a file never
reaches one.
Bear with it pls.
