What platform are you using to compile and run the programs? I use code blocks. How can I check the speed/ execution time and is the a better metric like mips that can be seen here?
I don't typically use an IDE. Just a text editor, build system (like make), and my compilation tools, all from the terminal. I explained this a bit more in a previous video (th-cam.com/video/Pqf6H1WSbeY/w-d-xo.html). I also have a video that goes over a few option for timing code. th-cam.com/video/1KQqpiXxvWQ/w-d-xo.html Hope that helps.
For Windows, CodeBlocks probably installed GCC using Mingw. You might need to put GCC into your system path in the Windows Environment variables. Then you can use the command prompt to compile. Yes, I know this is a year after you left your comment. Maybe this will help someone else.
I will test It with my window manager source code (dwm). It makes sense to make It faster. It already uses "-Os" flag but I am using "-O2" to see If It is faster. Looks nice up to now -- the first 10 minutes hahahah .
P.S.: I have encountered some problems with full-screen float windows, unfortunately. If you do not own the code or understands its mechanisms, do not make anything in the Makefile. You could, but there is a chance of the code not working, as in my case.
Man! These videos are helpful. Its not often you come across these resourceful videos as a learner or a student.
So straightforward and clear. Perfect
Thank you, Jacob. Nice, concise, and useful!

Nice! There's Os flag to make code smaller and Og to optimize for debug(?) :)
Amazingly useful!

superrrrrrrrrrrr da motta
Good, but you forgot -O4 and -Os.
-O4 and above on the compilers mentioned are just equivalent to -O3
