# Phone validation benchmark

v25.1.0, win32, Intel(R) Core(TM) i9-14900HX; Yup 1.7.1, Google 3.2.47, libphonenumber-js/max 1.13.14.

The frozen v1.3.2 adapter uses current Google metadata for a fair comparison. Both adapters share the same Yup instance. Each case runs 7 alternating samples of 1000 synchronous validations after 200 warmups. Ratios below 1 mean the new adapter is slower. Timing is informational; hardware, metadata and invalid-input exception handling affect results.

Equal-weight corpus ratio: 1.11x. Median cold adapter import: 25.73 ms old, 65.91 ms new (five fresh processes, excluding process startup).
