We use simd-json for SIMD-accelerated JSON parsing, which provides a 1.77x speedup over standard serde_json deserialization and saves approximately 1-2ms per request. Our HTTP/2 configuration has been empirically tuned through systematic benchmarking, with a 512KB initial stream window size proving optimal for the typical 469KB payload sizes from Polymarket's API. We've implemented DNS caching to eliminate redundant lookups, connection keep-alive management to maintain warm connections, and a buffer pool to reduce memory allocation overhead during request processing.
