  Google demonstrated that even a sub-second response time delay has a lingering impact on consumer engagement, even weeks after the site was increased again. A delay with this length might not be significant enough to warrant a crucial alert, nonetheless it includes a measurable effect on many metrics including revenue per user and user satisfaction.
  
  
  Around the same time as Google demonstrated this result, a study performed by Forrester Research and commissioned by Akamai unearthed that most consumers expect a website to load in under two seconds-compared to an expectation of under four seconds reported three years earlier. Over fifty percent of respondents stated that quick page loading was an essential factor for continued site loyalty.
  
  For reasons such as these, I believe it's important not to undervalue medium-term and long-term performance monitoring. Keynote has several features in this region including time record graphs, longterm trending, and service level reports. Let us take a look at all these capabilities in greater detail.
  
  Key-note holds aggregated net performance data and provides long-term development graphs for 2 yrs. Dig up new resources on a partner article directory by navigating to monitoring website. For example, I could tell that the performance of the Google webpage has been fairly consistent during the last couple of years, though lately website performance appears to be hovering closer to 0.5 seconds compared to the 0.3 second variety displayed in late 2008/early 2009.
  
  For medium-term analysis, Keynote keeps raw performance data for six months that people can analyze across a variety of dimensions using time record maps. Within the graph below, I've broken out the response time for the Google website over the last a month into times for DNS look-up, link, first byte download, and content download. As one would expect, of those elements, the one that requires by far probably the most time is content download.
