If you are using a Firefox (or other Mozilla-based) browser, you will be in for some pretty handy Google speed increases. Google has a feature whereby when you key a search term into Google it often has a pretty good idea of what it is you are looking for. This will be enhanced for Mozilla-based browsers, where Google will anticipate your selection and "prefetch" the target page content while it's waiting for you to click on its link. This will mean that there is a good chance that the page you are looking for has already been locally cached.

"Link prefetching is a browser mechanism, which utilizes browser idle time to download or prefetch documents that the user might visit in the near future. A web page provides a set of prefetching hints to the browser, and after the browser is finished loading the page, it begins silently prefetching specified documents and stores them in its cache. When the user visits one of the prefetched documents, it can be served up quickly out of the browser's cache."
