🔍 Methodology¶
Benchmarks are executed using pyo3 bindings. The Python interpreter overhead is included in the "Rust" times, making these results conservative estimates.
- Machine: macOS / Apple Silicon
- Python: 3.14.0 (via
uv)
🐍 fast_rich vs Python Rich (Drop-in Replacement)¶
The following benchmarks compare fast_rich (our drop-in Python Rich replacement) against the original Python rich library. These use the Python wrapper API with identical interfaces.

📊 Summary¶
fast_rich Performance Highlights¶
- Table (1000 rows): 73.8x faster than Python Rich
- Panel rendering: 13.8x faster
- Tree structures: 8.5x faster
- Overall: 3.5x-73.8x faster depending on workload
Key Optimizations¶
- Rust Core: Heavy computation done in compiled Rust
- Zero-copy where possible: Minimize Python ↔ Rust data transfer
- Efficient string handling: Pre-allocated buffers
- Cached rendering: Style and box calculations cached
