[appengine-java] Re: disable warmup-requests-enabled
Thanks for the reply , please tell me where is the option always On ? On Sep 14, 11:09 am, Simon Knott knott.si...@gmail.com wrote: Hi, I think you've misunderstood warm-up requests. GAE will spin-up and tear-down your application very often, especially if you have very little traffic going through. The warm-up requests are simply a mechanism for carrying out some initialisation, so that if a new instance is required to handle some additional load the main loading request is smaller in duration. By disabling warm-up requests, you are simply telling GAE that you don't support this initialisation optimisation. At the moment, there is an Always On option which allows you to always have three instances available. However, this will be disappearing with the new pricing structure at the end of the month.
