It'd depend on the type of freighter. There are 
freighters that are designed for fast transit 
with fast hulls and lots of engine plant. Those 
are usually ships that transport perishable cargo 
or cargo with some kind of rush to it. Some 
container ships fall into this category.

Bulk freighters are much higher on the scale of 
cargo to weight of ship with regards to power 
plants.

The nice thing about space craft however is that 
you're not having as much wear and tear on the 
ship. No salt water to rot out the ship in 20 
years.
