Tutorial for speed up Glossy Reflections?

it drives me mad it takes ages to render glossy effects.
i don´t know where to start to speed them up.

can you point me in the right direction?

use interpolated glossy

no way to get the normal glossy faster?
it´s very slow compared to other rendere.

are the default settings usefull or to high?

set subdivs to 3, and increase if that is too grainy. 50 is good for interpolation, but is way too much for normal glossy.

thx will try.

Yes, use low subdivs. Also the aa settings are important, because they smooth out the glossy effect too. I usually use low subdivs with high aa settings.
