I like this fact. I often do not have to optimize the CSS code, because the site is already fast enough. And often I have only 5-7 Javascript libraries in my full featured projects. Google PageSpeed says I have to reduce them, but an actual WordPress site has often over 20 Javascript libraries and are 10 times slower than my current projects.

You can see for yourself how thrustful Google PageSpeed is, if you get the tip to cache the Google Analytics Script. Please don't do this. And please don't upload the library to your server. This will work only for a while until Google will change something.

Better: Don't care about it.

If you are a perfect german guy (like me), it will stress you to read this message if you tweak your site to get a better page speed. You can use a trick to remove the message.

Put your Google Analytics Code inside of this:

<?php if (!isset($_SERVER['HTTP_USER_AGENT']) || stripos($_SERVER['HTTP_USER_AGENT'], 'Speed Insights') === false): ?>
<?php endif; ?>

This will not speed up your page, but will remove the message in the Google PageSpeed results.
