but on mine (Debian GNU/Linux with the latest Linux kernel and the latest GCC) the 
effect on -O0 is almost the same as on -Og for this particular benchmark.  I just 
tried again on the emacs-27 branch:

So when I want to compare Emacs 27 and Emacs 28 benchmarks, -Og builds
are off limits.  Now can I use O0 builds or do I have to use O1-O3
builds exclusively?
