Site accelerator
Jetpack’s new site accelerator is out of beta! All customers can now choose to serve their site’s static CSS and JavaScript files from our lightning-fast Content Delivery Network. This speeds up your site’s load time for visitors, alleviates the stress on your server, and makes your site friendlier to search engines.
i can’t see any reason why it wouldn’t work well with GP. But like all cache/optimizing plugins the settings need to be tweaked according to the server setups and the plugins you have in place. We prefer to keep these tools to a minimum and aside of Server caching/CDN would recommend autoptimize for speed improvements
