One of my colleagues on the AWS team responded to the original comment/question. Here's what he had to say:
The overall time is not linear as the Google Groups poster suggests. In most cases it will be between a few minutes to a few hours regardless of total size. Larger data sets may take a bit longer than smaller data sets simply because there is often more data movement to perform and coordination to be made across a greater number of machines. Rest assured though, we make use of parallelism where we can so the curve is far from linear. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
