I don't think it's that. My app is not so heavy. I have just one entity for now, there are no big operations, my user just saves to user entity, only one at a time. Sure, there are ways for improvement, like memcache, etc, but from App Stats it looks like database get is about 11ms, out of 600 total. So I don't think it's db problem. But I'd like to get some suggestion on finding what it is. Even my main page, which is just one image and login form, takes way too much to load [200-300ms].
