Google has recently announced the creation of a site aptly called, "Let's make the web faster." Google believes that web-pages that load faster will be visited more often (and they say they have data to prove it).
The new site offers many different tutorials and videos. Topics range from the more technical, prefetching resources, to simple, optimizing web graphics.
I know that I have some things that I can do to my site to make it load faster and will be using these resources.
Fortunately when I used Google's Page Speed Plug-in for Firefox, I found that drupal does a pretty good job of making your website run fast.
Check out the Google site.
