Performance Optimization Techniques in Software Development

This technical report discusses performance optimization in software development, particularly at the intersection of software and systems. It outlines various challenges faced by developers, including the difficulties in performance engineering and the non-deterministic results that arise from software code and systems infrastructure. The report references multiple studies and methodologies, such as performance testing practices and the importance of runtime data in development environments. It highlights the need for better communication between development and production teams to address performance faults effectively. Additionally, the report presents insights into tools like PerformanceHat, which integrates runtime traces into the integrated development environment (IDE) to predict the cost of new code before deployment. The document also touches on the role of generative AI in performance engineering, discussing initial studies that utilize large language models for performance optimization tasks. Overall, the report serves as a comprehensive examination of current practices and future directions in performance optimization.
