Sorry about misleading info. After configure I probably had forgotten one step
or was working with a dirty Work repertory.

Anyway, I did it again with "-Os"
and the produced binary now gives timings very much in line with your
binary from pretest, i.e. on this same test

real	0m1.700s
user	0m1.684s
sys	0m0.013s

typically

In comparison, the "-O2" binary produces this kind of timing

real	0m1.525s
user	0m1.509s
sys	0m0.013s
