Bottlenecks

What are the top performance bottlenecks in Windows likely to be?

We need to think about the fundamental resources in any computer and ask the question which is the main bottleneck.

• Disc usage - long term memory that persists for a long time
• Memory usage - short term memory for current tasks.
• CPU usage - central processing unit - the brain.

How do we check each resource and figure out which is the primary bottleneck?
