I did some update-heavy benchmarking recently, comparing Linux FSes,
and found that of (ext3, XFS, JFS), the fastest one, by a moderate
margin, was JFS.
It was not unexpected that XFS and JFS were faster than ext3; what was
a bit surprising was that JFS was quite a bit faster than XFS. The
last I had heard, JFS was considered pretty slow as it hadn't been
tuned too much; apparently that has changed.
I didn't get around to testing FreeBSD with soft updates; the downside
to that was, in my environment, and may also be, for you, that there
was a lack of administrative familiarity. We have too many "heads
exploding" from absorbing other things right now to be able to afford
to throw in the learning curve of FreeBSD at this point in time.
