# Performance
Performance optimization for bindcar and BIND9.
## bindcar Performance
Typical performance characteristics:
- **Latency**: 10-100ms per operation
- **Throughput**: 100-500 req/s per instance
- **Resource Usage**: Minimal (< 100Mi memory, < 0.1 CPU)
## BIND9 Performance
BIND9 is the primary performance factor:
- Query performance: 10,000+ queries/s
- Zone loading: Sub-second for small zones
- Zone transfers: Depends on zone size
## Optimization Strategies
- Use appropriate TTL values
- Minimize zone file size
- Optimize BIND9 configuration
- Use caching nameservers upstream
