Hi guys,

Sorry about the lag.  Here's an easy feature nobody has mentioned so far, and
from my reading isn't supported: separate journal, like Ext3.  The journals
stay per-node, but they can be on a different (shared) volume than the
filesystem proper.  This should be dead simple to do and it can make a huge
difference to write latency, by putting the journals on separate spindles or
(what I actually have in mind) in NVRAM.

Regards,

Daniel
