My Render is toooo slow

[cjswohong]

Hi Poor English. Sorry.

1. I make a scene like upper image. Render size is 1280*1770

But when I render that scene, that time is 1 hour and 40 minutes.

It looks insane and ridiculous.

I searched all tutorial and site about optimizing arnold render setting.

So I don't get it why this scene is too long time.

I'll give you scene file in mails if you want to.

2. And one more question. Can't arnold render low quality with low AA value?

If I set low AA value, I should add lots of sample in Diffuse and Specular to get rid of noise.

3. Last Question. Is render time same that 3,8,6 value in AA,Diffuse,Specular and 8,3,2 value?

※ Please don't tell me about denoiser and Adaptive sampling.
