Hi Steve, I will consult Upstream. Nevertheless, each time I have benchmarked -O3 against -O2 in the scientific packages I have packaged, I have never found a significative speed difference. I should probably do such a benchmark before contacting Upstream… -O2 is the default in Debian (Policy 10.1) and is enforced twice by our build tools. For most of our packages defining the optimisation level through CFLAGS, Upstreams choice is overriden anyway unless we took care of checking his makefile and eventually re-setting -O3.
