Speeding up gearhash on ARM64

Developers have explored ways to accelerate the gearhash algorithm on ARM64 processors. By rewriting critical sections in assembly and leveraging NEON SIMD instructions, they achieved notable speed gains compared with the original implementation. Benchmarks show reduced latency and higher throughput, making the optimized version more suitable for performance‑sensitive applications on modern mobile and server devices.
