Script Preparation code:

var sorted = new Array(200000);
var shuffled = new Array(200000);

class Vector { 
	constructor() {
      this.x = 0;
      this.y = 0;
      this.z = 0;
    }
}

for (let i=0; i<200000; i++) {
  const obj = { position: new Vector(), scale: new Vector(), rotation: new Vector() };
  sorted[i] = obj;
  shuffled[i] = obj;
}

for (let i=0; i<200000; i++) {
  const index = Math.floor(Math.random() * 200000);
  const temp = shuffled[i];
  shuffled[i] = shuffled[index];
  shuffled[index] = temp;
}

Tests:

Sorted
for (let i=0; i<200000; i++) { const obj = sorted[i]; if (obj.position.x === 0) {} }
Shuffled
for (let i=0; i<200000; i++) { const obj = shuffled[i]; if (obj.position.x === 0) {} }
Shuffled reorder
const reordered = new Array(200000); for (let i=0; i<200000; i++) { reordered[i] = shuffled[i]; } for (let i=0; i<200000; i++) { const obj = reordered[i]; if (obj.position.x === 0) {} }
