Like many benchmarks, you can game the benchmark, and you gamed the
benchmark. I guess you don't understand the technical details well
enough to get what's going on; we had a longer discussion of this a
while ago on this list.

I caught HP doing the same thing with lm_bench's lat_mem_rd benchmark
a while ago, and they immediately apologized and stopped using it in
their marketing literature. Which shows a lot of class.
