 🚧 **This implementation is incomplete and not ready for production use.** 
 
 Known limitations:
-- Performance is 2.08-3.96x slower than the mature `idna` crate
+- Performance is 2.00-4.09x slower than the mature `idna` crate
 - **Ada-idna is faster than idna crate for to_unicode conversion** ⚡
 - Some test cases fail due to expected value discrepancies
 - Unicode table data may be incomplete
