Hello,
You should use something a little more reliable like
gtmetrix.com
Good Luck.
That service isn’t perfect either (i.e. recommending Vary: Accept-Encoding on assets that are only served compressed), but kudos to them for responsibly advising:

1. Cache AddToAny Locally.
2. Use MaxCDN.
3. Install this plugin.
