Protocol Parsing

Same tool call, full field extraction (apples-to-apples):

Operation	Mean Latency	Throughput
JSON-RPC parse + extract	722.6 ns	~1.38M req/s
NDA-native parse + Merkle + extract	459.1 ns	~2.18M req/s
NDA speedup		1.6x

Shared Memory Throughput

Operation	Mean Latency	Throughput
JSON-in-shmem R/W	38.8 ns	25.8M ops/s
NDA-native shmem R/W	12.6 ns	79.2M ops/s
NDA speedup		3.1x

Concurrent Scaling

Threads	Throughput
1	2.86M req/s
4	7.01M req/s
8	12.7M req/s

vs Node.js MCP
