SysBench is ok when used properly, but UnixBench? They provide instructions on how you can patch and run it, using "./Run", but no warnings about what this is

SysBench is ok when used properly, but UnixBench?
They provide instructions on how you can patch and run it, using "./Run", but no warnings about what this is actually doing. See http://www.brendangregg.com/blog/2014-05-02/compilers-love-messing-with-benchmarks.html http://www.brendangregg.com/blog/2014-05-02/compilers-love-m... . I'd like to write a lot more about UnixBench, but I really don't have the time. It takes a lot of energy to refute this stuff.
If I were benchmarking OnMetal vs HW virt, I'd be showing a spectrum of micro-benchmarks, from equal performance (CPU) to network I/O. I'd expect some of my results to show a ~10x difference. You would then choose/weight them depending on what matters for your intended application.
