I recently moved my cloud endpoints project to java 8 .I am using objectify as my storage .I noticed some instabilities with the fetching of data from objectify . 1) The performance is ridiculously slow . 2) The loading of data with objectify from datastore throws 18:52:56.610 This request caused a new process to be started for your application, and thus caused your application code to be loaded for the first time. This request may thus take longer and use more CPU than a typical request for your application.
