Of late, my PowerBook has been running somewhat slow – scrolling through a PDF is less than zippy, and typing this into ecto is painful. I’m not quite sure what the problem with it — hopefully it’s not the SyncServer, iTunes seems to have red-hands too. While using top and digging around on the command line is, uh, “fun,” I thought I’d ask you, dear readers, if there are any silver bullets for answering the question “why is my Mac so slow?”
