# Sentry Performance Tuning

## Prerequisites

- Performance monitoring enabled
- Transaction volume metrics available
- Critical paths identified
- Performance baseline established

## Instructions

1. Implement dynamic sampling with tracesSampler for endpoint-specific rates
2. Configure environment-based sample rates (higher in dev, lower in prod)
3. Remove unused integrations to reduce SDK overhead
4. Limit breadcrumbs to reduce memory usage
5. Use parameterized transaction names to avoid cardinality explosion
6. Create spans only for meaningful slow operations
7. Configure profile sampling sparingly for performance-critical endpoints
8. Measure SDK initialization time and ongoing overhead
9. Implement high-volume optimization with aggressive filtering
10. Monitor SDK performance metrics and adjust configuration

## Output
- Optimized sample rates configured
- SDK overhead minimized
- Transaction naming standardized
- Resource usage reduced
