I recently found out that the new Google web accelerator drastically slows down Java Web Start. This is a problem that does affect the launch of GTO games. As this is a big downside to the accelerator at this point until either Sun Microsystems or Google make adjustments.
Doing a web search I found the following text that you can configure javaws.exe to use a direct network connection: open Javaws, click on the Preferences which will open the Java Control Panel, click on Network Settings, and change from Using Browser Settings to Direct Connection. There is a warning that this change should be done by advanced users so do this at your own peril.
