At this time, we do not sufficiently understand client usage patterns to accurately model overall performance improvement. However, we have selected a set of commonly used non-interactive applications that allow us to focus on the following three questions:

1.: Is operation shipping transparent to the applications?
2.: What is the extent of network-traffic reduction that can be achieved by using operation shipping?
3.: What is the extent of elapsed-time reduction that can be achieved by using operation shipping?

We shall answer these questions in the following subsections, after we briefly describe the experimental setup.
