btw., would be nice to look at it via tools/perf/ as well:

perf stat --repeat 3 ...

to see the basic hardware utilization (cycles/cache-misses, branch execution
rate, instructions, etc.) and the basic parallelism metrics, at a glance.

i suspect "perf stat -e L1-icache-loads -e L1-icache-load-misses" would give
us an even more detailed picture.
