Appengine has got two modes of operation.

High traffic applications are served directly out of the cache within
a second for example.

For low traffic applications first the uploded code has to be prepared
(unzipped for example) and put into the cache before it can be served.
Thus low traffic applications necessarly need a longer request time -
three seconds for example.

To my experience low traffic is everything below about 500 requests
per hour.

> New machine instantiations, which we all know happens quite frequently
New pages usually haven't a lot of visitors yet and thus are low
traffic apps. But a lot of longer existing pages have got low traffic
too.

Low traffic means additionally that each request consumes more
resources. Usually that doesn't matter as for almost all low traffic
pages these additional resources stay within the free quota.


--------------------
When comparing perfomance of different solutions it's important that
the solutions themselves are comparable.

If you don't need session management, user name, user account and
administration you probably don't need Django and should use a simple
and faster solution.

What concerns the performance of a Django solution my tests with the
aep-sample copied to my own appID three month ago varied
for high traffic between  0.5 - 1.0 seconds request time
for low traffic between 2.5 - 4.5 seconds request time

I would be very interested to hear of current test results.
