Please don't do performance related decisions based on data from
compiling code with optimizations disabled. Use -O2 or -O3 (or even
better, check both).
Options -O2 and -O3 interfere with profiling tools.

I will try using -Og the next time.
Just stop and use proper profiling tools like perf that can work with
optimized tools. You may have to compile with -fno-omit-frame-pointer,
but anything more than that is going to distort your measurement results
so much that they're worthless.
