I'd suggest minimizing the amount of duplicate links. If this is not possible, then consider using different labeling for each link.
For example, have the business logo at the top of your site as a link to the home page, and at the very bottom of the page, have a text link to the home page.
Also, you will want to configure your page so that code that isn't necessary right away should load AFTER the necessary code has loaded.
For example, Try something like this:
<!-- necessary code -->
<!-- enhancing code -->
