The Phoronix test suite is probably not helpful for schedulers. It runs a bunch of things one at a time, whereas schedulers care about dividing a shared resource among different things. It does a small number of samples and doesn’t do anything sensible with statistics to try to give you a useful number. It is a legendarily bad benchmark suite.
