Using Aov makes the rendering ~3x slower.

Hi. I noticed using aov is almost 3 times slower compared to using the same integrator without aov. Is that expected?

Hi @miangoleh

A 3x difference, does seem like a lot. There definitely is some overhead to using the aov integrator, the main reason that comes to mind is that it does an extra ray intersection with the scene to fetch the desired properties rather than using the one done by the underlying integrator. But that should be far from a 3x difference unless your integrator doesn't have any ray tracing at all.

I used two different settings. One with path and one with direct_projective. Both yeild the same results. I also replaced normals with albedo in another experiment.

spp was set to 8.
