Leverage browser caching Google Analytics

Question

I could find a new (at least new for me) code for Google analytics. If I understand, it loads in asynchronously (at least there is the word async in the code). I used that code in a page of my site and Google Page Speed still says: Leverage browser caching http://www.google-analytics.com/ga.js

Is that the the last and best code to keep track of your Analytics? What is the best way to put the Google Analytics and have a good response in Page Speed?

(you have to substitute UA-XXXXX-Y by your own code)

https://developers.google.com/analytics/devguides/collection/analyticsjs/

<!-- Google Analytics -->
<script>
(function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
(i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
})(window,document,'script','https://www.google-analytics.com/analytics.js','ga');

ga('create', 'UA-XXXXX-Y', 'auto');
ga('send', 'pageview');
</script>
<!-- End Google Analytics -->
