Developer builds CLI tool to detect and benchmark GDScript array performance pitfalls

A developer has released gd-bench, an open-source command-line tool that scans Godot project GDScript files to identify array usage patterns that can slow down game performance. The tool detects four categories of issues: untyped arrays, typed arrays, packed arrays, and dictionaries misused as arrays. Rather than simply suggesting rewrites, gd-bench generates runnable Godot benchmark scripts alongside each finding, letting developers measure actual performance differences before making changes. This approach addresses contradictory official Godot documentation, which gives conflicting guidance on whether packed arrays are faster or slower than generic arrays. The tool is installable via pip and includes 17 unit tests covering all finding types and edge cases.
