javascript - Ways to increase performance when set big value to innerHTML

Question

I'm trying to set a huge (200K) response to innerHTML of a node. The goal is to get better time than 2.7 sec in Internet Explorer 6.

Any ideas?

This won't make it happen any faster but it will stop the browser from locking up on the user; they can continue to use the page while this happens in the background:

function asyncInnerHTML(HTML, callback) {
    var temp = document.createElement('div'),
        frag = document.createDocumentFragment();
    temp.innerHTML = HTML;
    (function(){
        if(temp.firstChild){
            frag.appendChild(temp.firstChild);
            setTimeout(arguments.callee, 0);
        } else {
            callback(frag);
        }
    })();
}

Using it:

var allTheHTML = '<div><a href="#">.............</div>';
asyncInnerHTML(allTheHTML, function(fragment){
    myTarget.appendChild(fragment); // myTarget should be an element node.
});

This technique will take longer than plain innerHTML but the user will be able to carry on using your site without noticing a delay.
