Playing video online requires considerable computer resources compared to other
computer applications. This section alerts you to measures you can take to improve
performance and conserve system resources.
The video files are stored in your site’s AnswerBook2 directory. Each video file can
be as large as 10 to 30 Mbytes, or even larger. The size of the video file is displayed
next to the video icon. When you click on the video icon, AnswerBook2 launches the
video player for which your browser is configured. Once started, your video player
downloads the selected file to your local system, where it is temporarily stored in
your system swap space. When you quit the video player, the swap space is released.
Improving File Loading Time
Downloading video files can take anywhere from seconds to 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 bottom of your browser window will generally provide real-time
reports on what percentage of the file has been downloaded.
To improve access times to the videos, you can store the AnswerBook2 collection on
your local disk. Keep in mind that the size of the AnswerBook2 collection can be as
large as 660 Mbytes. If storing the AnswerBook2 locally is not an option, load times
will be improved by having the AnswerBook2 stored on the same subnetwork as
your own system. If you find the load times of videos are unacceptable, speak to
your administrator about storing the AnswerBook2 collection on your subnetwork.
Avoiding Using Proxy Servers to Access the
AnswerBook2 Server
Some web browsers are configured to use proxies. These proxies may slow down or
prevent viewing of the AnswerBook2 documents by the web browser. Normally,
however, proxies are used primarily to access external sites. In the unlikely event
that your browser does access the AnswerBook2 server through a proxy, perform the
