Note how the sets goes up, that means each run is getting cache misses
that lead to sets. In contrast, 1.9 sees no increase in sets after the
first run, so eveything is found in the cache and the hits percentage
gradually increases towards 100%. So 1.11 is faster than 1.9 even
though 1.11 seems to fail to caching everything.
