These options are automatically configured to the optimum settings for most users.
Some users may choose to change these defaults to experiment with potential perfor-
mance differences, or to minimize system overhead required by caching.
NOTE: Changes made to the customization options will only take effect after restart-
ing your computer.
Read Ahead Options
Read ahead caching (often referred to as prefetching) is designed to anticipate the next
request for data from the CD-ROM by reading information physically adjacent to the pre-
vious request. It functions in both forward and reverse directions. Read ahead caching
improves performance particularly for applications that are inefficient in how they han-
dle requests for data.
Disabled - Selecting this option will turn off all read ahead caching. Disabling all read
ahead caching may slow down file transfers when the requesting program is inefficient in
how it handles requests for data.
Small - Selecting this option will turn on read ahead caching using 2K data blocks. By
