Uint8Array	18393.8 Ops/sec

Script Preparation code:

var size = 1024;
var buffer = new ArrayBuffer(size);
var bytes = new Uint8Array(buffer);
var dv = new DataView(buffer);

for (var i = 0; i < size; i++)
  dv.setUint8(i, Math.ceil(Math.random() * 255));

Tests:

DataView
for (var i = 0; i < size; i+=2) dv.getUint16(i);
Uint8Array
for (var i = 0; i < size; i+=2) bytes.subarray(i, i + 2);
