Google AJAX API にAuto-Loading機能が追加されたらしい

Auto-Loading New!

It is possible to auto-load a list of APIs or Javascript libraries when including the loader script. This can be done in order to reduce the load time in many cases by eliminating a single Javascript request at load time. This advanced feature can be difficult to implement, depending on the exact situation. Therefore, we recommend that auto-loading only be considered in specific cases when a reduction in latency is crucial.

To use this feature, you can start with the configuration wizard. To use it manually, the list of APIs to load is specified in the initial <script> tag, rather than a separate google.load call for each.
