Lightroom 4 pegging 100% all the time, even with 1:1 previews rendered

I'm using two computers at work with identical hardware and software.

On one of them, light room pegs 100% with all 8 cores (hyper threading) for about three to eight seconds at a time.

I can't get much done.

I use grid mode and quick develop a lot and usually there's only a moment's delay before I can see the changes I've made.

It acts the same as it does if I try editing while exporting, importing, or rendering previews only I'm not doing any of those things.

According to the task manager, only lightroom is using the cpu, nothing else.

Any ideas?
