I think it's also worthwhile to look at the results of Tixy's file system
simulation before we switch. If there are significant performance regressions
over ext3 or if btrfs turns out to be much better than ext4, we should
probably not move to ext4 at this point but rather try to get btrfs fully
supported. My understanding is that there are other bugs that would need
to be fixed to make that happen.
