xfs as well (950 MB/s vs. 400 MB/s; that's more than a factor of two).
Sometimes, you have to make the engineering tradeoffs. That's why
we're engineers, for goodness sakes. Sometimes, it's just not
possible to square the circle.
I don't believe that the technique of forcing people who need that
performance to suffer in order to induce them to try to engineer a
solution which may or may not exist is really the best or fairest way
to go about things.
