This document tracks the performance evolution of fast-rich compared to the reference Python rich library.

📈 Performance Evolution (History)¶

Comparing Rust implementation speedups over time. (Values are speedup factors vs Python baseline. Higher is better.)

Table	15.0x	17.7x	59.3x	↗️ Massive improvement
Progress	6.0x	7.1x	61.8x	↗️ Zero-copy updates
Columns	20.0x	23.4x	45.1x	↗️ Layout engine rewrite
Logging	22.0x	24.4x	23.1x	➡️ Stable
Tree	10.0x	12.9x	19.1x	↗️ Recursion opt
Traceback	15.0x	17.6x	17.9x	➡️ Stable
Markdown	8.0x	8.6x	10.6x	↗️ Parser tuning
Panel	3.0x	3.4x	6.1x	↗️ Border rendering
Rule	4.0x	4.5x	4.8x	➡️ Stable
Syntax	1.8x	1.8x	3.4x	↗️ Cached themes
