# Pure Rust Concurrent Performance Profile
**Objective:** Identify bottlenecks and optimization opportunities in the pure Rust concurrent (rayon) implementation.
**Status:** To be completed (mrrc-u33.2)
## Profiling Targets
- Task distribution efficiency (rayon work stealing)
- Synchronization overhead
- Memory allocation under parallelism
- Thread utilization and context switching
- Batch boundary overhead
## Methodology
Use Criterion.rs with rayon profiling, Flamegraph, and thread-aware tools.
## Placeholder
This profile will be populated by running:
```bash
cd /path/to/mrrc
cargo bench --bench parallel_benchmarks -- --profile-time=10
```
See `scripts/profile_pure_rust_concurrent.sh` for detailed profiling workflow.
