There’s one problem with Gravatars. They are very slow to load. Each page with comments on them makes one call per comment to the Gravatar server. While a single call takes only a 100ms, on a page with hundreds of comments, we are talking about major slowdowns. Page loads can take 20 seconds and more.
This plugin solves this problem by:
<ul>
<li>
caching gravatars with WordPress cron job..
</li>
<li>
caching gravatars on comment submission
</li>
<li>
maintaining a single copy of the default gravatar instead of downloading it again and again for all the email addresses with no gravatar associtated
</li>
</ul>

Speeds up your website by making sure the gravatars are stored on your website and not loading from the gravatar server.
