Bandwidth and interaction
Users will not tolerate long delays. Research has shown that for most computing tasks the threshold of frustration is about ten seconds. Web page designs that are not well “tuned” to the network access speed of typical users will only frustrate them. Check your web site logs to be sure that you understand your typical user’s location and network connections. If you have many international users, for example, you may want to be more conservative about large graphics on your pages (fig. 4.16).
