2. Performance tuning - Wikipedia

   en.wikipedia.org/wiki/Performance_tuning

   Performance engineering is the discipline encompassing roles, skills, activities, practices, tools, and deliverables used to meet the non-functional requirements of a designed system, such as increase business revenue, reduction of system failure, delayed projects, and avoidance of unnecessary usage of resources or work.

3. Web performance - Wikipedia

   en.wikipedia.org/wiki/Web_performance

   Web performance optimization (WPO), or website optimization is the field of knowledge about increasing web performance. Faster website download speeds have been shown to increase visitor retention and loyalty [ 1 ] [ 2 ] and user satisfaction, especially for users with slow internet connections and those on mobile devices .

4. Program optimization - Wikipedia

   en.wikipedia.org/wiki/Program_optimization

   As performance is part of the specification of a program – a program that is unusably slow is not fit for purpose: a video game with 60 Hz (frames-per-second) is acceptable, but 6 frames-per-second is unacceptably choppy – performance is a consideration from the start, to ensure that the system is able to deliver sufficient performance, and ...

5. Performance engineering - Wikipedia

   en.wikipedia.org/wiki/Performance_engineering

   The term performance engineering encompasses more than just the software and supporting infrastructure, and as such the term performance engineering is preferable from a macro view. Adherence to the non-functional requirements is also validated post-deployment by monitoring the production systems.

6. Profile-guided optimization - Wikipedia

   en.wikipedia.org/wiki/Profile-guided_optimization

   In computer programming, profile-guided optimization (PGO, sometimes pronounced as pogo [1]), also known as profile-directed feedback (PDF) [2] or feedback-directed optimization (FDO), [3] is the compiler optimization technique of using prior analyses of software artifacts or behaviors ("profiling") to improve the expected runtime performance of the program.

7. Optimizing compiler - Wikipedia

   en.wikipedia.org/wiki/Optimizing_compiler

   Theoretical analysis indicates that some optimization problems are NP-complete, or even undecidable. [2] Also, producing perfectly optimal code is not possible since optimizing for one aspect often degrades performance for another. Optimization is a collection of heuristic methods for improving resource usage in typical programs. [3]: 585
