Apple Workgroup Server 8150/110 - Manual (Page 88)

What to do if your server’s performance decreases
If you notice a decrease in your server’s speed and general performance after
adding special software (a control panel, a system extension, or a custom
utility), it may be because your special software does not work well with
Power Macintosh computers.
To see if this is the problem, use the Extensions Manager control panel to turn
off individual programs and extensions, one at a time, and then restart the
server. (For information on using the Extensions Manager control panel, see
the “Setting Options” topic of Macintosh Guide, available in the Guide menu.)
If the computer performs better when a special program or extension is
removed, contact the software’s manufacturer for information or an upgrade.
If you still do not notice an improvement after removing all special programs,
try doing a “clean” installation of system software, as described next.
Doing a clean installation of system software
Performing what is commonly called a “clean” installation of system software
involves repairing any damage to your startup disk and installing new versions
of system software and disk drive software. To do this, you must start up your
server from the Workgroup Server Software CD-ROM disc. There are a
number of steps involved; here’s an overview of the entire process:
m Use the Disk First Aid program to inspect and repair your startup disk.
m Use Apple HD SC Setup to update the startup disk drive software.
m Use a special feature of the Installer to do the clean installation.
After the clean installation you can experiment with any special sofware you
used with the previous system software to see if you can use it without
decreasing the server’s performance.
WARNING If your startup disk has been formatted for use with Apple
RAID Software, do not use the following instructions for doing a clean
installation. See the Apple RAID Software Administrator’s Guide for
information about repairing disks and installing system software on
disks containing RAID volumes.
