Summary: Improving Performance

Key takeaways

• In this chapter, we learned not only how the new JIT compiler works but we gained an understanding of the traditional PHP interpret-compile-execute cycle. Using PHP 8 and enabling the JIT compiler has the potential to speed up our PHP application anywhere from three times faster and up.

• We also learned what a stable sort is and how PHP 8 implements this vital technology. By mastering the stable sort, our code will produce data in a rational manner, resulting in greater customer satisfaction.
