If you got that 8% number from Activity Monitor.app, then you should look
at its other tabs, too. If you got the 8% from something else, then try
Activity Monitor.app.
System Memory will show Page ins and Page outs. The latter tells if the
machine is swapping, which can be sluggish, depending on rate/sec. You
should also look at the pie chart for the amount of free or inactive
memory. It might also help if we knew how much RAM was in your machine.
CPU speed is just one factor in overall speed.
Disk Activity will show reads and writes to disk. If the machine is
swapping, you'll see lots of writing. If you see lots of unexplained
reading, it may be Spotlight indexing your drive (look for the dot in the
Spotlight icon).
Network Activity will show network transfers, including reads and writes of
mounted network filesystems (e.g. iDisk, network shares).
It's still possible for an app to be sluggish but not consume one or more
of the above resources. For that, use Sampler or one of the other
performance tools installed with Xcode. Use Spotlight to search for
Performance Tools.
