macOS Benchmark Snapshot

This page summarizes the current macOS benchmark

Environment:

  • Script runner: run_benchmarks.sh
  • Platform: macOS
  • Baseline: native Lua 5.5 on the same machine
  • CPU: macOS Apple Silicon M4 (by @sniper00)

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

Script Relative throughput
bench_arithmetic.lua 136%
bench_control_flow.lua 143%
bench_locals.lua 143%
bench_functions.lua 119%
bench_closures.lua 99%
bench_multiret.lua 105%
bench_tables.lua 141%
bench_table_lib.lua 301%
bench_iterators.lua 123%
bench_math.lua 140%
bench_metatables.lua 121%
bench_oop.lua 109%
bench_coroutines.lua 113%
bench_errors.lua 120%

Highlights:

  • The strongest macOS win in this run is bench_table_lib.lua, mainly because table.insert, table.remove, table.sort, and table.move all outperform native Lua by a large margin in the raw run.
  • bench_control_flow.lua, bench_locals.lua, bench_tables.lua, and bench_math.lua also show broad wins across most subtests.
  • bench_closures.lua is effectively at parity in this run.

String microbenchmarks from the same raw capture:

  • bench_strings.lua: about 99%
  • bench_string_lib.lua: about 120%
