I am now using 3.2-rc4 from Debian package already. Currently I do not build own kernels. I have the subjective impression that after the initial rebuild of the inode cache it became faster. I have the following mount options: deepdance:~> grep btrfs /proc/mounts /dev/mapper/deepdance-debian / btrfs rw,relatime,space_cache,inode_cache 0 0 /dev/mapper/deepdance-home /home btrfs rw,relatime,space_cache,inode_cache 0 0 Might be good to use noatime for harddisks as well. BTW on my ThinkPad T520 I do not perceive performance issues for BTRFS as /. But then thats located on an Intel SSD 320 where seeks should not matter much.
