[sdiy] SPICE and Processors

[JH.]

I don't know - when I started with analogue simlation, I often waited 
overnight, and bigger jobs were sceduled over the weekend ...

I've been doing a lot of analogue spice recently and in particular feeding
audio into the simulation and generating .wav files from probes. The
simulations are incredibly accurate but with a major drawback.. they take
ages. 10s of audio simulation might take 5 minutes!
       So here's the question, would a multi-core processor speed things
up? Is a Core 2 Quad 2.8GHz going to run simulations faster than a Core 2
Duo 3.0GHz or is it clock rate which counts? Do SPICE simulator engines
make use of multi-cores? I use Proteus for simulation. Thanks, George
