+![crabrl Performance](benchmarks/header.png)
+
 Lightning-fast XBRL parser that's **50-150x faster** than traditional parsers, built for speed and accuracy when processing [SEC EDGAR](https://www.sec.gov/edgar) filings.
 
+## Performance

+![Performance Benchmarks](benchmarks/performance_charts.png)
+
+### Speed Comparison
+
+![Speed Comparison](benchmarks/speed_comparison_clean.png)
+
+**Key Performance Metrics:**
+- **50-150x faster** than traditional XBRL parsers
+- **140,000+ facts/second** throughput
+- **< 50MB memory** for 100K facts
+- **Linear scaling** with file size
+
 ## Technical Architecture
 
 crabrl is built on Rust's zero-cost abstractions and modern parsing techniques. While established parsers like [Arelle](https://arelle.org/) provide comprehensive XBRL specification support and extensive validation capabilities, crabrl focuses on high-performance parsing for scenarios where speed is critical.
