It is not very useful. When I set it 3, gae will still only keep one idle instances, so my app will still encounter slow startup when 2 visits coming at the same time. Setting it higher is helpless to avoid the java app slow startup problem.
I just found the only difference between set "Max Idle Instances" as 1 and 3 is the total used CPU hours, about 25:29, which means except the free 24 hours, the total used CPU hours is 1:5. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
