 ### Added
 
 - **First-class strategies** `email`, `name`, `first_name`, `last_name`, and `phone` in config (same generators as `faker = "internet::SafeEmail"`, `name::Name`, `name::FirstName`, `name::LastName`, and locale-aware phone). Strategy names are normalized to lowercase at load.

 - **Random-path faker/phone/PII**: one reused `StdRng` on `AnonymizerRegistry` instead of re-seeding per cell.
 - **`faker` locale resolution**: `resolved_locale_key` avoids allocating a `String` per faker call when locale is `en` or absent.
 
+### Performance
+
+- Larger default I/O buffers; fewer per-line and per-row allocations on the SQL stream path (INSERT/COPY parsing and row filters).
