 //! Oxc Parser for JavaScript and TypeScript
 //!
+//! # Performance
+//!
+//! The following optimization techniques are used:
+//! * AST is allocated in a memory arena ([bumpalo](https://docs.rs/bumpalo)) for fast AST drop
+//! * Short strings are inlined by [CompactString](https://github.com/ParkMyCar/compact_str)
+//! * No other heap allocations are done expect the above two
+//! * SIMD is used for skipping whitespace and multiline comments
+//! * [oxc_ast::Span] offsets uses `u32` instead of `usize`
+//!
 //! # Parser Conformance
 //! The parser parses all of Test262 and most of Babel and TypeScript parser conformance tests.
