Hands-On High Performance with Go

Optimization strategies overview

In this book, we will also attempt to understand what exactly we are optimizing for. The techniques for optimizing for CPU or memory utilization may look very different than optimizing for I/O or network latency. Being cognizant of your problem space as well as your limitations within your hardware and upstream APIs will help you to determine how to optimize for the problem statement at hand. Optimization also often shows diminishing returns. Frequently the return on development investment for a particular code hotspot isn't worthwhile based on extraneous factors, or adding optimizations will decrease readability and increase risk for the whole system. If you can determine whether an optimization is worth ...
