I'm using btrfs since one year now and it's quite fast. I don't feel any
differences to other filesystems. Never tried a benchmark but for my
daily work it's nice. I also never had any issues with the memory. Imho
nowadays memory isn't a problem at all in desktop computers. I bought
8gb of memory 2 years before because it was so damn cheap. Never used
that mutch, but it was almost for free :)
The advantage to ext4 for me is the build in raid1 and the snapshots.
I'm using the snapshot feature for my local backups. I like it because
it's really easy and uses very few storage. A simple "Snapshot -> Rsync
to a different disk -> Snapshot" script is the perfect local backup method.
I really appreciate the work of the developers! Btrfs is great and I'm
110% sure it will become better and better over the next month.
Best regards,
Felix

Reading your post, at this point I'd actually recommend you stick with
ext4.
I actually shifted back from BTRFS to ext4 and fell like having offered myself
a brand new computer, about 20 times faster, me happy ;-)
Both btrfs and zfs are great, but IMHO btrfs is not ready for
daily use by "ordinary" user yet, while zfs is a memory hog
(especially for laptops, which is part of the reason why I'm using
btrfs instead of zfs on this one).
True, ZFS is excellent but a memory hog (and strongly advises using a 64-bit
OS) but I was surprised to discover that BTRFS was such a memory eater itself,
with kernel 3.0. My system was swapping like mad !
I use (kernel) ZFS on my 64-bit main machine and I'm plain happy with it, and
tried ZFS on my 32-bit laptop in the hope to get more performance for less
memory ; alas I just got a memory-hungry system running damn slow... For the
time being I will stick to ZFS for 64-bit machines with>= 4GB RAM, and to
ext4 for 32-bit systems with less RAM...
I don't feel that BTRFS gives any advantage in its current state of
development. Alas.
