Why is email so expensive?
I have an internal mail system, that will email the user when ever they
receive an email. Let say that I have 100,000 users that receive one email
a day. That is $10 per day in email cost alone. This seems extremely high
cost. I think I might have 10 times that

Could you create a Servlet that is loaded on launch, and set this kind of
property? I think this is a workaround until they can do it officially.

I am seeing the same error. I believe this happens when appengine shuts
down your server and then restarts the server. I have read the exception is
harmless, but the slow start seems to indicate different. My startup time
takes about 8 seconds.
I have created cron, that runs every minute.
I know that it is not possible to change the log format currently, but I
wanted to make a request for this feature.
Currently the default logging prints the class and method that makes the
call to the logging API. For me this always the same method, because I use
a utility method that adds the
application startup time.
It's also been suggested that we should look at a billing enabled option for
keeping a certain number of instances warm at all times.

There is a feature request to allow you to Pay to Reserve a JVM. They are
wanting to see if people would be willing to pay, and how much they are will
to pay.
If you are interested in this feature, please vote on the ticket and comment

I assume if a transaction is NOT active then NO read locks occur and
all updates are considered Singleton updates. Note that updates in
JDO are triggered by simply using a setter on a persisted Entity
attribute.

I have noticed that the first request to a server instance has really high
CPU usage (7000+ milliseconds). After the server is up, the same request
takes only 20 milliseconds. I am not using Spring or any other framework.
It appears that the time is used during the first execute call on a
with opening, closing and retrieving instances of
PersistenceManager.

Jason,
Thanks for the reply and checking the code. It is the null issue that is
causing this issue, but I had a second issue that I will start a new thread
for.
Thanks,
