Script Preparation code:

function generateDataset(limit) {
    let result = new Uint8Array(limit);
    for (let i = 0; i < limit; i++) {
        result[i] = i;
    }
    return result;
}

function decodeFrom(src, ptr) {
	return ((src[ptr] << 24) | (src[ptr + 1] << 16) | (src[ptr + 2] << 8) | src[ptr + 3]) >>> 0;
}

var time = 200;
var limit = 1000000;
var dataset = generateDataset(limit);
var view = new DataView(dataset.buffer);

Tests:

Dataview
for (let i = 0; i < limit; i += 4) { view.getUint32(i) }
Custom
for (let i = 0; i < limit; i += 4) { decodeFrom(dataset, i) }
