Apple Macintosh Performa 6360 Series - Manual (Page 103)

If your computer’s performance decreases
If you notice a decrease in your computer’s speed and general performance
after you install special software (a control panel, system extension, or custom
utility), it may be because the software is not compatible with Macintosh
computers built with the PowerPC microprocessor.
m To find out if a system extension or control panel is the problem, hold
down the Shift key while you restart the computer. This temporarily turns
off control panels and extensions. If the computer performs better without
these software items, one of them is likely to be the problem. (If you just
added new software, its system extension, control panel, or custom utility is
the most probable cause of the problem.)
To find out which software is the problem, use the Extensions Manager
control panel (in the Control Panels folder in the Apple [K] menu) to turn
off a system extension or set of extensions and then restart your computer.
(If you just added new software to your computer, its system extension is
the most probable cause of the problem.) For detailed instructions, see the
information about managing system extensions in the “Customizing Your
Computer” topic of Macintosh Guide, available in the Guide (h) menu. If
the computer performs better when an extension is turned off, contact the
extension’s manufacturer for information or an upgrade.
m Use the Memory control panel to turn off virtual memory. For more
information on virtual memory, see the “Memory” topic of Macintosh
Guide, available in the Guide (h) menu.
Note: If you turn on both virtual memory and RAM disk in the Memory
control panel, don’t set both of them at or near their maximum values.
Doing so can result in unpredictable or reduced performance by your
computer. (RAM disk uses random-access memory, or RAM, as if it were a
hard disk.)
If you still do not notice an improvement, you may want to reinstall system
software on your startup hard disk. See Chapter 7, “Reinstalling Your
Computer’s Software,” for instructions.
If you typically use several application programs at the same time, your
computer’s performance will increase if you install more random-access
memory (RAM). See Chapter 8, “Installing Expansion Cards or
Additional Memory.”
