Sourcemaps Lookup Laravel Package

title: Benchmarks weight: 7

Measured on an Apple M1 Pro (PHP 8.5.2), median of 10 runs, each in an isolated PHP subprocess to get clean peak memory numbers. axy/sourcemap 1.x is included as a baseline, since it's the main existing option for Source Map v3 work in PHP.

Scenarios:

• A: parse + 1 lookup (cold path).
• B: parse + 20 lookups across about 5 distinct source files (realistic stack trace).
• C: parse + 20 lookups on a single line in the middle of the map (worst case for lazy parsing. The first lookup must decode everything up to that line, the remaining 19 are cached).
