26 000 000, but way, way slower
55 000 000
somehow varying between these two
about 10 000 000 lower on both numbers after some repeated running, but still a variance. Seems to converge on slightly less than 20 000 000
extremely variable basically

131 000 000 +- 5 000 000
basically B by row is slow, but not necessarily poor cache, at least not l3 cache.
There is something happening that we don't see. Record cache stuff at another level?
LLVM managing to optimize better with B by column?

interesting thing: the large amount of L3 misses in rowrow apparently doesn't matter much
these give correct results asymptotically, but other differences are not really visible
