Has anyone done any bechmarks? Is the cache really helping that much? If
it doesn't, and it performs similarly to other journaling FSes that do
not use this much RAM, well, if it's not waste then what?

Does it guarantee the same atomicity that UFS does? Is it OK to run an
email server on it? Will I lose messages in cases of powerfail/crash?
