Very low. My main comment is that doing a good job of benchmarking is a
very difficult job. The complications are far too many and subtle to
explain in a simple posting. If you don't understand them, you can get
numbers that make no sense at all, and are off by orders of magnitude.
People spend quite a long time learning about the subject.

It just isn't worth the time to try to even explain the issues here.

You are better off to run real applications of interest to you instead
of small artificial benchmarks. Your real applications are something
that other people won't be doing for you (unless you happen to know
other people who use the same applications).

No thanks. I don't think I want to contribute to spreading what I expect
to be dat aof questionable use. There are lots of people already in the
benchmarking business. I don't think this one will make a significant
positive contribution.
