The aim is to use the web traffic statistics to figure out how well or how poorly your site is working for your visitors. One way to determine this is to find out how long on average your visitors spend on your site. If the time spent is relatively brief, it usually indicates an underlying problem. Then the challenge is to figure out what that problem is. Explain the effect of data rates on each part of the network Explain the terms latency, response time and jitter and describe their effect on overall network performance and on the performance of your chosen organizations network. In web performance circles, “latency” is the amount of time it takes for the host server to receive and process a request for a page object. The amount of latency depends largely on how far away the user is from the server. For obvious reasons, tackling latency is a top priority for the performance industry. There are several ways to do this: * Allow more requests to happen concurrently. * Shorten the server round trips by bringing content closer to users. * Reduce the number of round trips. * Improve the browser cache, so that it can (1) store files and serve them where relevant on subsequent pages in a visit and (2) store and serve files for repeat visits. Jitter is the amount of variation in latency/response time, in milliseconds. Reliable connections consistently report back the same latency over and over again. Lots of variation (or
