Are you sure your problem is CPU rather than memory usage? There is a
lot of caching in grads v2 that tends to set your memory "watermark"
quite high (some of this you can control).  Are you running on a 32 or
64-bit OS?

It would be nice to have a side-by-side benchmark of v1.9 and v2 as a
way to identify possible bottlenecks we need to pay attention to.
