Not sure about the performance issue, but either way, don't use RAID5/6
with btrfs for anything else than playing around. The code is not
finished.

No, not for raid5/6.

Use md-raid5 which is known and true, and put btrfs on top.
And still have backups, be ready for btrfs to become unusable (speed
and/or deadlocks), get trashed, or some other problem.
It's not guaranteed to happen, but the odds are far from being 0 either,
so either your data is throwaway, or have good backups.
