## Latest Results (2026-02-10)

Apple M4 Pro, 48GB RAM, macOS 15. hyperfine 5 runs + 2 warmup.
119+
All times in milliseconds. These are **cold start** measurements (process
120+
launch to exit) — languages with heavy runtimes (JVM, V8) pay startup cost.

CW wins vs Java: 20/20, vs Python: 18/20, vs Ruby: 20/20, vs Node: 20/20.
146+
147+
\* Java times are dominated by JVM startup (~20ms). Warm JVM execution
148+
is significantly faster. C/Zig/TinyGo are native-compiled (AOT) baselines.
149+
150+
Note: gc_stress Zig value (414.6ms) omitted — Zig benchmark uses
151+
`std.AutoArrayHashMap` which is not comparable to GC-managed collections.
