# Code optimization

> Project configuration, design patterns, and coding strategies to help optimize the performance of your code.

Considering performance in all the code you write helps your project scale without bottlenecks. There are several ways you can improve performance, including avoiding bad practices, [profiling](/engine/6000.7/manual/analysis/profiler.md) your code, implementing appropriate design patterns, and using techniques like asynchronous programming to split work across multiple threads of execution.
