-### Notable Victories
-
-- **Ackermann function: 5.25x faster** - Deep recursion handling
-- **Bitwise operations: 2.70x faster** - Efficient bit manipulation
-- **Fibonacci recursive: 2.68x faster** - Optimized function calls
-- **Arithmetic operations: 2.61x faster** - Fast numeric computation
-- **Array sum: 2.06x faster** - Optimized array access
-- **Primes: 2.03x faster** - Efficient loop execution
-
-Started at 1402ms for Fibonacci(30). After optimization: 219ms. **6.4x improvement**.
-
-### Three-Way Benchmark: Rava vs Python vs Java
-
-5-run averages comparing Rava interpreter against Python 3 interpreter and Java OpenJDK (JIT compiled):
-
-**Note:** Java uses Just-In-Time compilation to native machine code, while Rava and Python are pure interpreters executing bytecode. Despite this unfair advantage, Rava still manages to beat Java at string concatenation and consistently outperforms Python across most benchmarks. This demonstrates the effectiveness of Rava's interpreter optimization techniques: NaN-boxing, fast frames, method caching, superinstructions, and bounds check elimination.
