neither, I did it manually. ok, the new test result: 1. if I remove all jar files from the war/WEB-INF/lib, the warmup time is about 2.3 seconds. 2. if I put the only the core app engine sdk jar file in war/WEB-INF/lib, but doesn't reference it, the warmup time is about 2.9 seconds. 3. if I put "DatastoreService datastore = DatastoreServiceFactory.getDatastoreService();" in the jsp file but do nothing eslse, the warmup time is 3.5 seconds 4. if I put a query in the default jsp file, the warmup time is 4.7 seconds. 5. if I convert query result as list, the warmup time is 6 seconds. so, I think it is very clear that the datastore API is main cause of long warmup time. A simple datastoe calling will increase the warmup time much. In above example, the total increased warmup caused by datastore APIs is more than 3 seconds. Otherwaise, scanning the core app engine sdk jar will cost 0.5 second. So, @GAE_team, please optimize your datastore APIs.
