Apple Macintosh Performa 6300CD Series - Manual (Page 80)

If your computer’s performance decreases
If you notice a decrease in your computer’s speed and general performance
after you add special software (a control panel, system extension, or custom
utility), it may be because the software does not work well with Macintosh
computers built with the PowerPC microprocessor.
m To find out if the new software 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 this software, one
of these items is likely to be the problem.
m Use the Extensions Manager control panel to turn off a system extension or
set of extensions. For detailed instructions, see the “Setting Options” 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.
m If you use several application programs at the same time, your computer’s
performance will increase if you install more RAM (random-access
memory). See “Expanding Memory” in Chapter 3.
If you still do not notice an improvement, you may want to reinstall system
software on your startup hard disk. See the Macintosh Performa CD booklet for
instructions.
