Any benchmark is going to be a benchmark of the OS as much
as it is going to be a benchmark of the filesystem. It's pretty
hard to separate the two.
ZFS is best tested on Open Solaris. UFS is best tested on FreeBSD,
EXT3 is best tested on Linux, and HAMMER of course is best tested on
DragonFly. Plus the OS itself will depend greatly on whether the
machine environment is UP or SMP.
