Compiler auto-vectorization performance relies on pointer aliasing checks. Programmers can use the 'restrict' keyword in C to optimize code and avoid runtime checks.
Improving memory access time is crucial. Programmers should understand techniques like caches, prefetching, and data alignment to optimize performance beyond what compilers can automatically do.
Using integer arithmetic instead of floating-point can enhance program speed significantly. CPUs often excel in integer arithmetic due to better bandwidth.
