"I've been writing C for quite some time, but I never followed good conventions I'm afraid, and I never payed much attention to the optimization tricks of the higher C programmers. Sure, I use const when I can, I use the pointer methods for manual string copying, I even use register for all the good that does with modern compilers, but now, I'm trying to write a C-string handling library for personal use, but I need speed, and I really don't want to use inline ASM. So, I am wondering, what would other Soylenters do to write efficient, pure, standards-compliant C?"

I've dealt with plenty of "don't worry I'm a game developer, I'm the best kind of programmer there is" programmers, your post is almost cliche. It's almost entertaining to tear their illusions down on StackOverflow, because they are so full of themselves, both when asking and answering questions. It's easy to spot them, because they always start their posts with "I'm a game programmer".
Here are some hard truths:

About the points you make:
1) I'm not bragging about anything, and probably would be getting more in another field, for example yours. I'm glad for you. I'm also glad so many people suffer the "not invented here syndrome" that brought to the development of all the libraries you use, because thanks to that we are not still eating bananas in a tree.
2) My post says clearly to profile to know what functions are the time hoggers, investigate to write better algorithms and disassemble them to know how your compiler interprets your code, to be able to write them in the best way you can think. I'm surprised that my post was too long to read for someone who writes code in as few time as possible for a living and to accomplish goals, as you should surely have more time than me. Now tell me about wifes and kids. Yeah, I have these too, and still can afford to spend some extra time studying my own code to improve it.
3) I understand painting walls and facades is not what you study at beaux-arts at the university. There are many types of people who use paint. All are necessary, and all are respectable. There are many types of people who use a compiler, too. There are many metrics you can use to measure code quality, but we were talking about maximum speed, and if you truly think anything I said is in detriment of good code quality I'm afraid you have a deep understanding problem, a programming problem, or both, but in any case you would not last too much at my job place. Not that you would want to get it, of course. Usually people painting facades get much more than these trying to change the world with a brush. I also compose music. Maybe not an art, also, because you can hit bongos with your balls
No need to be angry with the rest of the world, dude

"The world is full of differences, learn to bare with it."
Indeed, if we all bare with it then some major differences that split the world population in two will become obvious.
