Web Performance in Practice - Why We are Waiting
Web browsing is the application producing most of the traffic observed
on the Internet backbones today. While this is obviously an enormous
success for a single application that was created only a decade
ago, many users experience Web access as a ``world wide waiting'' process.
In this paper, statistical evidence based on two long-term
IP traffic traces is given for the amount of
waiting time which is due to different phases of a Web connection --
domain name lookup, connection establishment, requesting and
finally transferring an item. Nearly half the delay
in an average HTTP/TCP connection is due to the first three components
and only the rest can be influenced significantly by higher speed
access systems for large downloads.
