Yes!! I was waiting for someone to say this because I wasn't sure if that was the correct term to use! (I know nothing about advanced crap like that, haha) Also, back in the days of Tiger, I recall Netkas (I think) dealing with some setting inside the kernel that had to do with processor timings. I wonder if I can go that far back on his site and find what he was talking about? This is exactly the kind of thing that needs to be investigated.

Question Ianxxx, what are you doing with your system while it is unhooked from internet? Any apps, anything intensive? And when it IS connected to the internet, what are you doing? And what if you simply connect it to the internet and walk away? Would it still slow you down? After the slowdowns, are you seeing anything excessive in Console? Anything repeating? Any "CODE SIGNING" messages? Sorry for so many questions, but they're all important
