But then why optimizations would matter? If the program is fast, 
you won't improve it by improving performance by 2 times: it will 
remain fast, and if it's slow, it's probably an algorithmic 
complexity. You said it yourself that to get performance from C 
you need extensions, it's not provided by C semantics itself.
