yes. this is expected. These two numbers are single run
on cold cache, so there will be run-to-run variation.

These two and the first two were the ones I was interested in,
since they do many iterations over the same set and
the best to compare code gen changes.
The delta % is actually better than I expected judging by test_bpf
micro-benchmarks, so the results are very encouraging.

Thanks!
