What is Performance Driven Development and why aren't you doing it? - James Seconde
Learn how to adopt performance-driven development (PDD) and break free from the misconception that it's only for big projects. Discover the culture shift and tools needed to prioritize performance optimization from the start.
- Performance-driven development (PDD) is not widely adopted due to the misconception that it is only for big companies or complex projects.
- PDD is not just about performance, but about creating a culture that prioritizes performance, performance testing, and performance optimization from the beginning of the project.
- The cost of PDD is not just financial, but also includes the time and effort required to implement and maintain it.
- PHP developers are particularly guilty of not adopting PDD due to the simplicity and speed of the language leading to a lack of understanding of performance optimization techniques.
- Debugging and testing tools such as Xdebug, Tideways, and Blackfire can make a huge difference in identifying and fixing performance issues.
- Performance testing should not be an afterthought, but part of the development process from the beginning.
- Many developers are not aware of the importance of monitors and logs in performance optimization.
- Having a strong culture of performance and prioritizing it from the beginning of a project is crucial for success.
- E.g., at Laravel, they have a culture of performance and it is part of the core of the framework.
- PDD can be used in any project, not just big ones, and it can bring significant benefits such as faster development, better testing, and improved code quality.
- PDD is not a one-time thing, but an ongoing process that requires constant attention and optimization.
- DevOps and performance engineering are not mutually exclusive, and PDD can help bridge the gap between the two.
- Performance testing should be done not just in development, but also in production, and monitoring should be an ongoing process.
- Many developers do not understand the importance of the underlying technology stack and how it affects performance.
- Performance optimization should be a key consideration in the development process, not an afterthought.
- PDD can be used to improve the performance of existing applications and systems.
- PHP developers often ignore the performance aspect of their code, leading to slow applications and frustrated users.
