Actually no, after your message I swapped kernels again to recheck, and nope,
now the one with simd_relax removed appears faster a bit as it should be (by
about 5%).
Perhaps it was something else, maybe my test bench is not ideal: both
"dual-core" VMs run on the same 8-core FX-8350, which has some of its cores
coupled to share resources, so at the scheduler's whim VMs can probably affect
each other. (Will try further tests with affinity pinning).

With respect,
