I know this isn't a super-scientific test, but, I wanted to get an

with different filesystems, using, or not using fsync()'ing all over
the fileserver...

Yes, that really is a 4x performance boost on writes. w00t, as the
kids say...
Being one of these "w00t" saying kids, I can state similar speed
improvements in vos moves between our servers, which are now nearly all
running 1.4.2 namei + fsync patches on sun4x_510 (with the single
exception of a lone Debian machine using back ported 1.4.2 packages
without mods.) Volume moves of certain largish volumes with lots of
small files used to take literaly 3 hours and the vos move time has now
been reduced to a few minutes or in some cases 10s of seconds. A
significant improvement. I'm all for getting these patches into the 1.5
branch and into a stable release at some point in time. We have not
encountered any problems as a result of these fsync mods and hope others
are willing to try them out as well.
