I just upgraded to Solaris 10 Update 10, and one of the improvements
is "zfs diff".
Using the "birthtime" of the sectors, I would expect very high
performance. The actual performance doesn't seems better that an
standard "rdiff", though. Quite disappointing...
Should I disable "atime" to improve "zfs diff" performance? (most data
doesn't change, but "atime" of most files would change).
I tend to disable atime in the root filesystem and only enable it on a
filesystem if required. So far, it has never been required on any of
the systems I look after!
