    I was just wondering if anybody else has had performance problems with viewing PDF files in Preview. For some reason on my Alu 2.0 iMac it is incredibly slow. Scrolling through even a small PDF, say 10 pages, is painfully sluggish. Activity Monitor reports 70-80% CPU usage when I am scrolling. The PDF I'm viewing isn't anything special either, just your basic black lettering on white. This is driving me nuts. I don't remember it being so slow when I've viewed PDFs before.

    Any thoughts?

    I haven't had any issues like that, but I do hate how Preview doesn't animate animated .gifs.

    Preview.app implements Apple's own algorithms for rendering PDF files. As a result, when it comes to high resolution documents containing plenty of pictures, Preview.app will occasionally struggle. The easy way around this is to get a different reader that implements Adobe's rendering engine such as Acrobat for Mac.

    That make sense, but this is just a simple and small PDF. No images, nothing fancy to render, just a basic document that could be punched out of a word processor in a few minutes.

    Guess I'll have to give reader a run.
