When working with software performance optimization, I use these 9 + 1 core principles as a checklist to make sure I have looked through the performance gain opportunities reasonably thoroughly.

The performance difference between an unoptimized and a fully optimized software system can be a factor 10 to 100. Even a factor 1.000 if the right conditions are present.

Better performing software means lower hardware costs, and less environmental footprint.
