1. Convert to a 16k or 32k leafsize.

How should I do this ? Can I do this on a live FS, and isn't this going
to double my on-disk used space (I have active snapshots...)

I think you need to backup, reformat and restore from backup for now.

2. defragment (each non-trivial file) every now and again

I believed that the "autodefrag" mount option was supposed to avoid the
need for manual defrags...?

In theory yes. But AFAIR it is currently limited to certain usecases.

Plus, with respect to snapshots, isn't this going to increase a lot my
used disk space ?

I don´t think so, but I will leave this to a developer to answer.

3. Note that btrfs in kernel 3.6 (vs 3.5) does appear to be quite a
bit quicker.

I'm not sure that "a bit" quicker will be enough, when I see my BTRFS
is currently about 8x slower than what ext4 user to...

How did you measure this? Is this just the boot times you mentioned in the 
original article?
