I have a fairly simple app - it looks up a couple of objects from the
google datastore and then creates a page from django template - pure
vanilla.
I wanted to see how my app would perform under heavy load, so I set up
a simulation where 500 virtual web-browsers would attempt to request
my page
additionally, under this load, the time it takes to service a request
grows from 2 seconds per request (no load) to 15 seconds per request
(high load).

Since this is just a test app, can you post the code (perhaps to Pastie

Hi Keiya,
In looking at the HTML for that page,
One thing that has become apprent is appengine, is designed to scale
under real world usage.
So if your App went from 0/1 users to 500 in a matter of seconds, then
the system wont work well. You need to ramp up the usage slowly.
Even a slashdotting would result in a 'ramp' usage.

All datastore operations in a transaction must operate on entities in

No, datastore can't do it.
An entity is stored in the datastore as a key: value pair. Its value is
