How to Speed Up a Marin 29er?

My wife has a Marin mountain bike with 29-inch wheels. The tires are Serfas Drifter 29x2.0.

The bike is really slow.

I ride behind her on my mountain bike, 26x1.75 Continental Contact tires. When we coast downhill I have to start way behind her, slower, and then brake to stay behind. She is waaaay slower coasting than me. It's not a drafting thing, I'm much too far behind for that. Something about the bike.

She tried my bike today and had an instant 3+ mph gain.

We worked on her bike's geometry, which was part of the problem, but those tires suck speed. I can feel it when I take hers out for a test ride.

Any ideas for speeding up the bike? I tried searching for 29er tires, didn't find much.
