E.5 Improving Online Video Performance
Playing video online requires considerable computer resources compared to other
computer applications. This section informs you about resources, and alerts you to
measures you can take to improve performance and conserve system resources. To
find out about each topic, go to:

E.5.1 Video Files and Your System Resources
On Sun systems, the video files are loaded into your AnswerBook2 server’s directory.
Each video file in this AnswerBook2 document can be as large as 60 Mbytes. The size
of the video file is displayed next to its video icon in the AnswerBook2
documentation.
When you click on the video icon, AnswerBook2 downloads the file to your local
system’s /tmp or /swap directory, and then launches the video player for which
your browser is configured.
On Sun systems, usually the system administrator often configures the /tmp or /
swap directory to be about twice the capacity of the system memory. On the Sun
system where you will be viewing these videos, make sure that the system
administrator configures the system /tmp or /swap directory to support playing
video files as large as 60 Mbytes.
When you quit the video player, the /tmp or /swap space is released. If you do not
quit the player, then it is possible for your /tmp or /swap directory to become full.
We recommend that you quit the player after watching each video.
E.5.2 Improving File Loading Time
Downloading video files can take a few minutes, depending on the size of the file
and the amount of network traffic. Because load time is so dependent on your
network environment, it is impossible to be more specific. The status bar at the
