I have listed the whole and exact commands used for to get these
results. I've just cut some fat from the report to make them easier to
read and compare.

Follow Reimar's advice and see what counters are available for your
CPU. I suspect that some of these counters are actually hardware debug
registers, so they may not be available on older CPU's.

I'm happy to see you working on improving the code.

Unfortunately the PSU of my old PC burnt out, so it won't be easy for
me to do more tests. I just hope that the rest of the old PC is not
damaged.

BTW, the illegal instruction you were talking previously... can you
confirm if you get it when using -march=native ?
I also had issue with "native" when using `distcc`, but that's kind of expected.
