That's fine, but all we're asking for is "don't dump those requests into an instance that isn't able to serve the request immediately". If there are three instances running and one being started up, don't consider the latter in the population of instances to send requests to. Dump it into an instance level queue that is already running. Everything else remains constant. I stand to be corrected, but I doubt that Google searches are dumped onto cold instances. They and Amazon conducted the research on how delay time affects user behaviour. If Brandon's unique searches make Google slow, that's a separate issue from instances waking up. And I doubt Google slows down too much on long-tail queries. I just searched on "Just to be clear, I am agreeing with you in that the GAE scheduler" and it took: 1 result (0.21 seconds) -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
