I've seen apps sustain around 800 QPS for 12 or 13 hours with little
issue.  There are a lot more issues that start to bite you as your QPS
increases, both on the front-end and back-end processing.  It is
important to have a well thought-out design.  If your app is able to
return _very_ fast from most requests, GAE is an OK choice.


You would definitely need to work with the GAE team to get many quotas
and limits significantly increased for your application.  There are a
lot of backend per-minute limits that a lot of people probably never
need to think about.
