Google's commitment towards offering faster services has ensured that the +1 button is not left out. Since its launch in June 2010 Google claims that they have been working extremely hard to enhance it's load time.
Talking about the load time of +1, Google's David Byttow, announced, “Today, we’re proud to announce two updates that will make both the +1 button and the page loading it, faster.”
The first of the two updates is, Google has started to roll out a set of changes which will enable the button to load up to 3 times faster than before on your website. For these changes to take effect you do not require to take any actions yourself. Google has done the job for you. So all you have to do is just sit back and reap the benefits of the button loading faster than it previously did.
The new asynch snippet is available at + Configuration Tool. The image above shows the code being included below the last <g:plusone> tag for the best performance.
So, sit back and enjoy the speed!
