Your iBook might be set to save energy, which reduces processor performance. You can change this setting to optimize processor performance in Energy Saver preferences.
To change the processor performance setting:
Choose Apple menu > System Preferences, and then click Energy Saver.
Click Options. If you don't see the Options button, click Show Details.
Choose Highest from the Processor Performance pop-up menu to allow your computer to work at its fastest.
Setting the processor performance to Highest uses more energy, so your battery may run out more quickly.
Also, the files on your hard drive may be fragmented to a point that it is causing the slow down. Although the installer does some optimization after OS updates, it does not optimize the entire drive. Use a program like Drive 10 or TechTool Pro 4 to optimize the drive for better performance.
