I was recently witness to a benchmark of 7.4.5 on Solaris 9 wherein
it was apparently demonstrated that fsync was the fastest option

If there's a way to make this information more useful by providing
more data, please let me know, and I'll see what I can do.
What would be really interesting to me to know is what Sun did
between 8 and 9 to make that so. We don't use Solaris for databases
any more, but fsync was a lot slower than whatever we ended up using
on 8. I wouldn't be surprised if they'd wired fsync directly to
something else; but I can hardly believe it'd be faster than any
other option. (Mind, we were using Veritas filesyste with this, as
well, which was at least half the headache.)
