Alembic SOP Slow CPU Cook

I know it’s still an experimental build, but any idea why I might be getting super slow CPU cooks with it?

A relatively simple (108 vertices) mesh with some minimal transform animation is spiking at 40+ ms during playback. Interpolation, and compute normals is set to None. Transform is set to Dynamic.

Tested on my i7700 Razer Blade w/ 1060 GTX, as well as a custom Xeon E5-2673v3 server w/ M6000. Both produce same results.

Any thoughts?
