It's worth noting that there are definitely exceptions where loop unrolling is a good practice for optimization. When writing code that will run on obscure old architectures, and even some common ones, the CPU doesn't have things like branch prediction and caches, and your compiler is likely quite rudimentary. As always, profiling is key.
