Benchmark: ArrayBuffer vs JSON serialization 5M

Tests:

JSON serialization
const arr = Array.from({ length: 5000000 }).map(() => Math.random()); const serialized = JSON.stringify(arr); const deserialized = JSON.parse(serialized); deserialized.map(x => 0.0); const serializedAgain = JSON.stringify(deserialized);
ArrayBuffer serialization
const arr = Array.from({ length: 5000000 }).map(() => Math.random()); const buffer = new ArrayBuffer(arr.length * 4); const view = new Float32Array(buffer, 0, 4); view.map((_, idx) => arr[idx]); view.map(() => 0.0); const view2 = new Float32Array(buffer, 0, 4);
