Google +1 buttons to be 3 times faster

An update on the +1 button is going to make sharing 3 times faster.

First, we’ve begun to roll out out a set of changes that will make the button render up to 3x faster on your site. No action is required on your part, so just sit back, relax, and watch as the button loads more quickly than before.

In addition to the improvements made to the button, we’re also introducing a new asynchronous snippet, allowing you to make the +1 experience even faster. The async snippet allows your web page to continue loading while your browser downloads the +1 JavaScript. By loading these elements in parallel, we’re ensuring the HTTP request to get the +1 button JavaScript doesn’t lead to an increase in your page load time. For those of you who have already implemented the button, you’ll need to update the code to the new async snippet, and then you should see an overall improvement in your page load time.

To generate the new async snippet, simply visit the +1 Configuration Tool.
