**Profile Data**: Representative HFT workload (backtest + ML training + benchmarks)

|
## Expected Improvements
|
|
|
|
| Benchmark | Before PGO | After PGO | Improvement |
|
|
|-----------|------------|-----------|-------------|
|
|
| Order Matching | TBD | TBD | TBD |
|
|
| Authentication | TBD | TBD | TBD |
|
|
| Order Submission | TBD | TBD | TBD |
|
|
| API Gateway Proxy | TBD | TBD | TBD |
|
|
| DBN Data Loading | TBD | TBD | TBD |
|
|
| TFT Inference | TBD | TBD | TBD |
|
|
|
|
**Target**: 5-15% improvement in CPU-bound hot paths
|
|
|
|
## Next Steps
|
|
|
|
1. Review benchmark results in `target/criterion/`
|
|
2. If improvements meet expectations (5-15%), deploy PGO builds to production
|
|
3. Update CI/CD pipeline to use PGO for release builds
|
|
4. Consider BOLT post-link optimization for additional 2-8% gains
