1.2 Ghz Intel single core? What about time sharing? I suspect Google squeezes in a lot of instances in each physical server, so that with time sharing of the CPU the instances in reality get a lot less than that when the load is high, and judging by how often instances are swapped in and out of servers, it means that there are way too few physical servers to handle the practical load.
Compare with a virtual memory. If there is too little physical memory, the page swapping algorithm, no matter how good it is, will have to do a LOT of swapping of memory pages. And what do we see the GAE instance scheduler do? A LOT of instance swapping. Not only that, we as customers have to pay a large part of that page swapping, plus poor performance when the traffic to the application is low. AND, much if not most of the actual specs for the instances is kept hidden from us customers. So it's very hard to tell what we actually will be paying for, plus Google can change the specs at any time without adjusting the price model. It's opaque as hell. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
