I am not sure if the stack is overflow but mouse wheel is scrolling slow in home page of a website I designed in Google chrome. Is there some html or css property controlling the scroll speed or this is a performance issue?

the site address is ragaimen.com and the problem occures in first page (other pages work fine).

We are facing the same issue after updating to the latest Chrome (94.0.4606.61, but someone else reported this happened from version 91), if your have a marquee on your page, it's very likely to make your mouse wheel scrolling slowly, and we believe it's Chrome's bug.

for chrome using, you can try opening chrome://flags/#smooth-scrolling and disable 「Smooth Scrolling」function.

for javascript solution, you can try the following code but actually not very smooth scrolling, I hope someone can improve it:

function wheel(event) {
      var delta = 0;
      if (event.wheelDelta) {(delta = event.wheelDelta / 120);}
      else if (event.detail) {(delta = -event.detail / 3);}

      handle(delta);
      event.returnValue = false;
  }

  function handle(delta) {
      var time = 100;
      var distance = 140; //adjust this for your page

      $('html, body').stop().animate({
          scrollTop: $(window).scrollTop() - (distance * delta)
      }, time );
  }

if (window.addEventListener) {window.addEventListener('DOMMouseScroll', wheel,  {passive: false});}
if (document.addEventListener) {document.addEventListener('DOMMouseScroll', wheel,  {passive: false});}
if (window.addEventListener) {window.addEventListener('mousewheel', wheel,  {passive: false});}
if (document.addEventListener) {document.addEventListener('mousewheel', wheel,  {passive: false});}

2021-10-01 updated: Chrome version 94.0.4606.71 has fixed this problem.
