I have a late 2008 Macbook with Core 2 Duo and plenty of RAM and HD space. (8GB of RAM, max for my machine)
Every time I do some work in iPhoto and Aperture, my CPU usage goes up to around 60-80% eaten up by those apps. They weren't as responsive as when I was on Snow Leopard. This started happening since I upgraded to iPhoto '11.
I'm thinking of upgrading to an SSD, would that improve my iPhoto performance? I doubt it because it seems that iPhoto is CPU, not IO, bound. Has anyone else tried this?
