Impact of GCC optimizations on resource consumption

Hi all,

I am studying the impact of GCC optimization options on CPU & memory
consumption of compiled programs.

Executing code compiled with O3 is it always so greedy in term of resources ?

Is there any scientific reference or specification that shows the
difference of Mem/CPU consumption of different optimization levels?

People working on this problem often focus on the impact of these
optimizations on the execution time, compiled code size, energy, etc,.
However, I can't find too much work talking about resource
consumption.

Thanks in advance.
