Consider Cost -- Higher performance = higher cost -- Find sweet spot: diminishing returns point -- Factor in operational costs (maintenance, complexity) - -### 4. Test Under Load -- Use realistic load profiles -- Test with expected peak load + 50% headroom -- Run sustained tests (1+ hour) to detect memory leaks - -### 5. Validate Horizontally -- Test scaling before relying on it -- Verify load balancer overhead is acceptable -- Check for resource contention at higher instance counts - -### 6. Database Tuning -- Test PostgreSQL upgrades in staging first -- Tune shared_buffers based on available RAM -- Monitor connection pool usage during tests - -### 7.

This caused uvicorn.access logger to always log at INFO level regardless of LOG_LEVEL environment variable. This caused massive performance degradation (~75x slower) during high concurrency because every HTTP request was logged at INFO level, creating severe I/O bottleneck. Fix: Read self._level from settings.log_level at start of initialize() method, BEFORE configuring uvicorn loggers. Now uvicorn.access correctly respects LOG_LEVEL.

Prerequisites and setup instructions (curl, jq, hey) - Quick start test script covering all major endpoints - Individual endpoint tests (health, auth, tools, servers, resources, prompts, profile) - Performance testing with hey load testing tool - Benchmarking scripts for measuring throughput - Expected performance baselines (1500-2000 RPS for authenticated endpoints) - Troubleshooting guide (token expiration, validation) - Advanced scenarios (continuous monitoring, deployment verification, load testing) - Integration with existing automated test suite All commands are CLI-ready and tested. Complements automated tests in tests/performance/ with human-readable examples for development and debugging workflows.
