50-performance — Performance
5 skills in this category.
db-tuning
Database performance tuning: index analysis, query plan optimization, connection pooling, and configuration tuning.
profiling-analysis
Analyze application performance using profiling tools, traces, and logs to identify bottlenecks and hotspots.
progressive-execution
Return fast approximate results immediately (Phase 1), then enhance with slower enriched results (Phase 2). Phase 1 is standalone. Phase 2 is optional enhancement. If Phase 2 fails, Phase 1 stands.
resource-awareness
Monitor memory, CPU, time, and rate-limit constraints. Adapt behavior gracefully — degrade, shed load, switch algorithms. Prevents runaway resource usage and cascading failures.
