while i'm not FreeBSD coder i would ask question - how does it REALLY
work - contrary to information.
i mean how it works in practice.
IMHO checksumming every data (not just metadata) is nonsense if it cannot
be turned off. this makes every transfer not just I/O bound but CPU and
memory transfer/cache bound too. while disk and memory bandwidth in todays
machines are quite comparable (memory is faster but not THAT faster than
linear disk I/O) it isn't just "a little thing".
built in compression isn't good idea IMHO - of course it doesn't hurt if
it's optional. today disk space is rarely a problem, while huge files are
often not much compressible.
by general description filesystem looks very nice.
thats theory - did anyone made a real test on real system?
