Google App Engine - Does a new instance of a user launch so that it waits for its initialization?

I know that when your Google App Engine (GAE) application works with 0 instances (since it was inactive for bits) and the user requests a page, the user has to wait for the instance to load and make all instances that can make the user wait a significant amount time.

My question is about the situation when your GAE application already has 1 instance, but begins to experience a heavy load and starts loading the second instance.

In this case, what will happen:

  • Will the user end up waiting until an instance of the second instance is created before responding to the request?

  • Will requests be sent to the second instance until it is fully created, so the user will not wait for a longer time?

EDIT: Unfortunately, the answer to this question is No. 1 at the moment. However, there is a function request to change the behavior to # 2. Please run this function request ( http://code.google.com/p/googleappengine/issues/detail?id=2690 ) to attract the attention of App developers Engine
