Oh please don't go there. Do you honestly think you (in general) are smarter at

generating microprocessor instructions than a multi-million hour compiler software?

If the execution speed is acceptable, I will always prefer readability of the source code

over execution speed. I don't really care if some function can be executed 1ns faster
if

several functions were collapsed into one.

 

If I could trade a 1 second added boot up time (~8 second total then?) for readable

ReactOS source code, I would do it immediately ;-)

Using smaller functions instead when we are only using the code once, may help on
readability but can cost speed and space. (Think
of what standard code C uses to enter and exit a function.) But then again, you can get
around that by using declaring those
functions as inline.

The functions are too large then. Use more smaller functions instead.
