Performance Engineering Standards
Universal standards for high-performance software development across all frameworks.
Priority: P1 (OPERATIONAL)
Universal standards for building high-performance software across all frameworks and languages.
🚀 Core Principles
- •Efficiency by Design: Minimize resource consumption (CPU, Memory, Network) without sacrificing readability.
- •Measure First: Never optimize without a baseline. Use profiling tools before and after changes.
- •Scalability: Design systems to handle increased load by optimizing time and space complexity.
💾 Resource Management
- •Memory Efficiency:
- •Avoid memory leaks: explicit cleanup of listeners, observers, and streams.
- •Optimize data structures: use the most efficient collection for the use case (e.g.,
Setfor lookups,Listfor iteration). - •Lazy Initialization: Initialize expensive objects only when needed.
- •CPU Optimization:
- •Algorithm Complexity: Aim for $O(1)$ or $O(n)$ where possible; avoid $O(n^2)$ in critical paths.
- •Offload Work: Move heavy computations to background threads or workers.
- •Minimize Re-computation: Use memoization for pure, expensive functions.
🌐 Network & I/O
- •Payload Reduction: Use efficient serialization (JSON minification, Protobuf) and compression.
- •Batching: Group multiple small requests into single bulk operations.
- •Caching Strategy:
- •Implement multi-level caching (Memory -> Storage -> Network).
- •Use appropriate TTL (Time To Live) and invalidation strategies.
- •Non-blocking I/O: Always use asynchronous operations for file system and network access.
⚡ UI/UX Performance
- •Minimize Main Thread Work: Keep animations and interactions fluid by keeping the main thread free.
- •Virtualization: Use lazy loading or virtualization for long lists/large datasets.
- •Tree Shaking: Ensure build tools remove unused code and dependencies.
📊 Monitoring & Testing
- •Benchmarking: Write micro-benchmarks for performance-critical functions.
- •SLIs/SLOs: Define Service Level Indicators (latency, throughput) and Objectives.
- •Load Testing: Test system behavior under peak and stress conditions.
