Hi,
we recently debugged a performance issue with Guice 3 running on the App Engine. I don't want to go into the details, but it turned out that our app on GAE is faster (both initial startup + warmup requests) when Guice is ran in Stage.PRODUCTION than in Stage.DEVELOPMENT (the default stage when you do not set a stage explicitly). We actually expected that Stage.DEVELOPMENT would be faster because a lot of binding is then done on-demand. But this was wrong - at least for our applications. So - if you are using Guice you can try to start your injector in Stage.PRODUCTION. Please also share any insights you may have on this. Thanks, Raphael The thread were we discussed the issue: https://groups.google.com/forum/#!topic/ninja-framework/IHs5wUQEQsI More on Guice Stages: https://google-guice.googlecode.com/svn/trunk/latest-javadoc/com/google/inject/Stage.html -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
