📊 Local Benchmarking

Required before every PR: Run local benchmarks to validate performance and prevent regressions.

# One-time setup (installs pre-push hook for automated validation)
make setup-hooks

# Required before every push (enforced by pre-push hook)
make ci-fast

# Required before every PR (performance regression detection)
make bench-local

Performance Budgets (automatically enforced):

• RPC p95 latency: ≤ 15ms
• Transaction p95 latency: ≤ 50ms

The make bench-local command runs local Slonana and Agave benchmarks, then validates performance against strict budgets. PRs that regress p95 performance beyond these thresholds are automatically blocked.

See Contributing Guide for complete development workflow requirements.

📊 Performance

Metric	Agave	Slonana	Advantage
RPC Latency	5ms	7ms	Agave 1.4x faster
Memory Usage	1,230MB	10MB	Slonana 123x less
CPU Usage	35.8%	4.7%	Slonana 7.6x less
Startup Time	2.02s	2.02s	Equal

4. Additional Enhancements

• Fixed GlobalProofOfHistory race condition during validator shutdown
• Enhanced activity injection to prevent idle validator shutdowns
• Added comprehensive error handling and environment detection
• Implemented both text and JSON output formats for programmatic analysis

Key Findings

Slonana Advantages:

• 123x lower memory consumption (critical for resource-constrained environments)
• 7.6x lower CPU utilization (better scalability potential)
• Exceptional micro-operation performance (2.4M+ ops/s for core operations)
• Container-native deployment without system configuration requirements

Agave Advantages:

• Slightly better RPC response latency (5ms vs 7ms)
• More mature production ecosystem and tooling compatibility

Impact

The benchmark infrastructure now provides reliable performance comparison between Agave and Slonana validators in any development environment, with both validators successfully running without special system configuration. This enables continuous performance monitoring and optimization tracking for the Slonana C++ implementation.

Recent Production Fixes:

• ✅ Segmentation faults eliminated - Fixed dual identity storage and bounds checking
• ✅ Real snapshot downloads - Replaced 2GB mock files with actual network downloads
• ✅ Hardware wallet support - Real Ledger/Trezor integration with cryptographic operations
• ✅ Prometheus metrics - Full implementation with proper format validation
