they appear clearly that the best choice for GAE is java, if scalable feature is what we are looking for.

my question is, What are the implications that will affect on performance if we use one of frameworks?

e.g.

 django     --> python
 spring MVC --> java
 slim3      --> java
 ... etc

Answer 1

Just a quick note - don't take this as a definitive/comprehensive comparison:

Both Django and Spring have a long startup time, which can lead to requests being dropped. I'd go with a framework that was speciffically made for GAE: tipify, slim3, etc..
