Poor Performance from CD-ROM-Based Program (141368)
The information in this article applies to:
- Microsoft Windows Millennium Edition
- Microsoft Windows 98 Second Edition
- Microsoft Windows 98
- Microsoft Windows 95
This article was previously published under Q141368 SYMPTOMS
When you run a program that accesses a CD-ROM drive, you may notice that
the program is not performing optimally. You may notice slow data transfer
in a business or reference program, or skipping or slow audio and video in
a multimedia program.
CAUSE
This behavior can occur when the Supplemental Cache Size and Optimize
Access Pattern For settings are not be set correctly for your CD-ROM
drive.
RESOLUTION
To resolve this issue, follow these steps improve your CD-ROM drive's
performance:
- Click Start, point to Settings, click Control Panel, and then double-
click System.
- On the Performance tab, click File System.
- Click the CD-ROM tab.
- Move the Supplemental Cache Size slider to the right to allocate more
random access memory (RAM) for caching data from the CD-ROM drive or to
the left to allocate less RAM for caching data.
Note that many multimedia programs perform better with a smaller cache
because these program tend not to reuse data.
- For reading continuous data, such as .avi files, use a higher setting
in the Optimize Access Pattern For box. For reading random data,
increase the Supplemental Cache Size setting and decrease the Optimize
Access Pattern For setting.
- Click OK, and then click Close. When you are prompted to restart your
computer, do so.
NOTE: If you are using real-mode drivers for your CD-ROM drive, these
settings have no effect.
