I posted a blog entry about improving startup times when using JPA. http://bpossolo.blogspot.com/2012/08/reducing-google-app-engine-cold-start.html
Quick summary of my results: Dev Mode on local machine: went from 16 second startup time to 2 seconds Production GAE: went from 50+ second startup time to 7-8 seconds My application uses GWT, JPA and several other small libraries that do not impact startup time. I have about 29 entity classes and I wire up all my components manually in a context listener. ABout 98% of my entire startup time is attributed to creating the EMF which I use to perform some initialization logic. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
