Benchmark: Object function binding vs global scope lookup

Script Preparation code:

const QUEUE_1 = new Map([
  [{}, {}],
  [{}, {}],
  [{}, {}],
  [{}, {}],
  [{}, {}],
  [{}, {}],
  [{}, {}]
]);
const QUEUE_2 = new Map([
  [{}, {}],
  [{}, {}],
  [{}, {}],
  [{}, {}],
  [{}, {}],
  [{}, {}],
  [{}, {}]
]);

let BUFFER = -1;

function run() {
  QUEUE_1.clear();
  QUEUE_2.clear();
}

let c = 0;
const cancel = function(n) { c--; };
const request = function(fn) { fn(); return ++c; };

var OBJECT = {
  _buffer: -1,
  _queue1: new Map([
    [{}, {}],
    [{}, {}],
    [{}, {}],
    [{}, {}],
    [{}, {}],
    [{}, {}],
    [{}, {}]
  ]),
  _queue2: new Map([
    [{}, {}],
    [{}, {}],
    [{}, {}],
    [{}, {}],
    [{}, {}],
    [{}, {}],
    [{}, {}]
  ]),
  runGlobal() {
    cancel(BUFFER);
    BUFFER = request(run);
  },
  runBoundOwn() {
    cancel(this._buffer);
    this._buffer = request(run);
  }
};
