How much time does a dishwasher save?

I've lived long stretches without a dishwasher, but I love having one. To me it seems like a superb

time-saving appliance, but not everyone agrees. Dishwashing by hand rarely occurs in a single chunk of

time, so it may not be obvious how much time it takes to wash an entire load.

To conduct a fair test, I decided to wash the same load twice. Dishwashers vary, but I believe mine is

typical. It held the following:
5 glasses
2 jars
6 mugs
3 bowls
3 ramekins
3 large knives
a spatula
a cheese slicer
2 shot glasses
cup measure
tupperware lid
six plates
8 bowls
1 tupperware container
cutting board
1 travel cup
30 utensils
