I personally would consider zfs on freeBSD as unstable/experimental on
everything apart from AMD64's with loads of RAM to spare. I have tried tuning
for large files UFS offers near-raw performance.
it can't be much better.
it can be less efficient on concurrent operations because MAXBSIZE is
128KB on FreeBSD.
i don't know why it's still that small!
i changed
#define MAXPHYS (128 * 1024) /* max raw I/O transfer size */
to
#define MAXPHYS (1024 * 1024) /* max raw I/O transfer size */
on EVERY machine i own (except those having <128MB RAM) and it works fine,
while there are huge difference.
you WILL saturade gigabit ethernet port with just 2 gstriped drives
and many concurrent users fetching files.
make sure gstripe use huge stripes not small (like 256MB), to speed up
multiple concurrent access instead of single linear read speed.
