It very much depends on how full the freezer is and how solid the fill is. A representative test using a 70's model freezer with 12 lbs and then 100 lbs of ice is shown here: www.nooutage.com/freezer.htm
Do expand the images to see how the freezer was loaded and the chart of temperature change.
Newer freezers probably have better insulation and will warm wore slowly but the effects of loading will be very similar.
They also have a page that compares the start and run currents of fridges, freezers and well pumps - good to know if you're planning to have backup power: www.nooutage.com/start.htm
www.nooutage.com is in the business of selling backup power systems of all types and sizes but they also have some useful info on their site.
