I just want to confirm that I am also seeing the same issue with a
similar setup. I also tried with the priority boost fix we previously
posted, the results are slightly better, but we are still seeing a very
high variance.

On average, the results I get for 10 30-seconds runs are still much
better than nosmt (both sysbench pinned on the same sibling) for the
memory benchmark, and pretty similar for the CPU benchmark, but the high
variance between runs is indeed concerning.

Still digging :-)
