Oh, and just so we are clear that I'm not Attacking.
2.7 works really well with instances turning off. AND not burning me on spin-up by "Over compensating" for spikes. When you are "sizing" your app it doesn't appear there is any advantage in picking more than 2 Idle instances. And honestly I'm having a hard time coming up with a reason to set more than 1 min idle instance. This information is specific to 2.7 Thread Safe Python. I haven't tried this test on other configurations. -----Original Message----- From: google-appengine@googlegroups.com [mailto:google-appengine@googlegroups.com] On Behalf Of sb Sent: Saturday, November 26, 2011 3:48 PM To: Google App Engine Subject: [google-appengine] Re: Idle instances do not turn off automatically. Please help It doesn't behave this way at all. It just fires up a new instance once the resident instance get overloaded. The resident instance goes idle. The new instance then handles all the traffic, and when that gets overloaded another instance is created, while the original resident instance is just sitting their completely idle. So I am getting billed for three instances one of which is doing nothing and never will do anything until I manually intervene.
