That is irrelevant; for example the register allocator made the compiler
slower (initially even 3 times, but we managed to reduce it to a few ten
%), but had great effects on code quality.
The most expensive optimization you can effect with -O is the assembler
optimizer, this is noticable in compilation speed.
However, debug info is for example something that affects speed more.
