HTML Preparation code:

<div id="points-body">
    <div data-players="10" data-players-n="1 098" data-raids="11" data-raids-n="9 604" data-dps="15 165.5" data-dps-r1="15 701.6" data-points-dps="96.59" data-points-raids="99.90" data-points-players="99.18">
    </div>
</div>

Tests:

element getAttribute
var element = document.getElementById("points-body").querySelector("div"); let i = 1000; while (i--) { element.getAttribute("data-points-dps"); }
Cache dataset beforehand
const element = document.getElementById("points-body").querySelector("div"); const dataset = element.dataset; let i = 1000; while (i--) { dataset.pointsDps; }
Access dataset on each call
const element = document.getElementById("points-body").querySelector("div"); let i = 1000; while (i--) { element.dataset.pointsDps; }
