My experiences of Google AppEngine usage : Svarichevsky MikhailTests were done on 20 concurrent requests from 2 different servers at the same continent. Averages for 7 seconds of execution. Some might say "Hey! They are not terrible, my [place url here] could handle just 2 hits per second, so even 38 is a nice upgrade". Well, first of all, this is hello-world class application. It is as simple as possible. Real application would have 5-25 memcached/datastore
