what's your solution to the performance hit that you get when you load up the dom with a zillion things? long, unvirtualized threads will bring every decent computer to its knees.

the sites could implement their own search to make it all work if they wanted to. they just dont. but blaming virtualization is not tit.

The solution is to improve the browser to remove the performance hit. Modern computers are extremely powerful so there is no good reason why they would not be able to handle a zillion things in the DOM.
