Windows Benchmark Snapshot

This page contains the current Windows benchmark snapshot that used to live in the main README.

Environment:

• Script runner: run_benchmarks.ps1
• Platform: Windows
• CPU: Ryzen 7 5800X
• Baseline: native Lua 5.5 on the same machine

Method:

• Values are shown as luars / native Lua * 100
• 100 means parity with native Lua
• 120 means luars is about 20% faster
• 80 means luars is about 20% slower

Notes:

• This is a script-level summary from the current Windows run of run_benchmarks.ps1.
• String-heavy microbenchmarks are intentionally left out of the chart because several subtests complete too quickly on Windows timer resolution, which can distort summary ratios.
• For full raw output, run run_benchmarks.ps1 directly and inspect the per-subtest numbers.
