Mac OS X slowdown and repair

Our 2.0ghz Aluminum Macbook has ben going slow for months, spinning beachball, lag and generally enough frustration that even my 9 year old son was complaining. If you are experiencing a similar poorly performing Mac, try this tip;

Start up from your OS install disk and run a Disk Repair on the Startup disk, not a Repair Permissions, a Repair disk that is only available when starting from another disk.

In our case the disk repair found only a couple of errors but the difference in performance is amazing, we have a new Macbook on our hands as I couldn't believe the difference such a simple function provided.
