sadly, this was similar to my experience as well, and we shut it off and simply used public caching (aka Cache-Control: public etc.)

Page speed works like Beautiful soup + a CDN

 

If you don’t have a sucky page template, and you serve mostly unique content, page speed will slow you down a lot.

 

The request hits the Page Speed Caching Proxy, the caching proxy grabs the page from Appengine, the proxy recalculate the HTML, then serves the user.

 

For a “miss” to the cache you have the Appengine time, Plus the HTML clean up time.

 

Unlike “good” cdn solutions Page speed doesn’t do anticipative caching, where the cache of popular content is kept warm automatically so users almost never hit an uncached page.

If you use all of GWT's client bundle options then you already have the effect (and more) of PageSpeed. Automatic image sprites, embedded resources, embedded css, etc. Running all of this through PageSpeed again is just wasting a lot of work to re-do what is already handled by GWT's compiler.
