Is subdivision single threaded?

Hi!

I have a scene with alot of scattering, both standins/instances and regular copy to points.

Time to first pixels is getting pretty long, close to 5 minutes. Most of that time only one thread is working in the task manager. Could that be my subdivisions? Or is it more likely IO, textures and standins and such?

best,

More likely file IO for the standins.

An Info-level Arnold log would show more details.
Subdiv is multi threaded.
