A methodical process for detecting, analyzing, and eliminating performance bottlenecks in software and infrastructure.
Performance tuning is a structured method to identify and remove performance bottlenecks in software and infrastructure. It combines measurement, analysis and targeted optimization steps to improve latency, throughput and resource efficiency. Use cases include operations, release optimization and architectural improvements. Focus is on measurable goals and repeatable actions.
Time within which 95% of requests are served; important for user perception.
Number of processed requests per second under defined load.
Resource utilization to assess efficiency and capacity needs.
Concrete case: Reduced P95 latency through DB indexing and query refactoring.
Partial load distribution and schema design reduced write locks and increased scalability.
Introduction of a multi-level cache reduced bandwidth needs and improved response times.
Define goals and KPIs
Measure baseline and identify bottlenecks
Prioritize, implement and validate measures
Plan rollout and adjust monitoring
