A profiler is a performance analysis tool that measures the behavior of a program as it executes, particularly the frequency and duration of function calls.
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.
Caching is a fundamental method of removing performance bottlenecks that are the result of slow access to data.
Caching improves performance by retaining frequently used information in high speed memory, reducing access time and avoiding repeated computation.
Caching is an effective manner of improving performance in situations where the principle of locality of reference applies.
The methods used to determine which data is stored in progressively faster storage are collectively called caching strategies.
Distributed computing and clustering can negatively impact latency while simultaneously increasing load on shared resources, such as database systems.
Self-tuning systems have been a hallmark of the aerospace industry for decades, as this sort of feedback is necessary to generate optimal multi-variable control for nonlinear processes.
