Here are the top 10 discoveries about the Internet that Keynote Systems has made while measuring web-site performance for our customers and partners with our Keynote Perspective service. 1.ÿ The Internet delivers on-demand Web content, on average, at 5,000 characters per second (click here for details). This is approximately the bandwidth of the latest generation of 56 kbps modems. This suggests that improving bandwidth to the home via cable-TV or satellite modems may not give users much of an improvement over 56 kbps modems until Internet throughput is improved. 2.ÿ Performance experienced by users varies greatly depending on the metropolitan areas in which they are located. Our measurements indicate that users in Phoenix, Dallas-Fort Worth, Houston, Kansas City, and Miami metropolitan areas tend to experience worse response times than users in other metro areas accessing the same web servers. This correlates with the scarcity of fiber-optic cable and other infrastructure deficiencies in these areas of the United States. 3.ÿ Internet performance problems are generally not server problems. For many web sites, Keynote's measurements demonstrate that most of their performance problems occur out in the Internet's infrastructure somewhere between the web site and its users: at the NAPs (Network Access Points) where backbone providers interconnect, in one or more routers along the communication path, or in a DNS (Domain Name Service) close to the user. 4.ÿ CompuServe, CWIX, SAVVIS, and other less-well-known backbone providers currently offer some of the fastest Internet backbone services. We believe that's because their backbones are relatively underutilized compared to those of larger providers such as Sprint and InternetMCI. Large, capacious, well-engineered backbones (just like most of our freeways) can perform more slowly than others if they have to service more customers at once. 5.ÿ Internet brownouts, such as those caused by the rash of backhoe construction accidents in July, produce measurable performance degradation for all users. However, the Internet still continues to operate, albeit more sluggishly, while the accident damage is being repaired and traffic is re-routed around the accident scene. 6.ÿ Many large commercial web sites are connected to the Internet via multiple backbones. They want assurance that users will still be able to get through to the web site even if one of their providers experiences an outage or backhoe incident. 7.ÿ Deploying a mirrored web site in Europe to serve European users may not increase performance for those users. Our measurements show that a web server geographically close to its users can often deliver worse performance than a more geographically remote server. 8.ÿ The vast majority of large commercial web sites run Netscape's web server software. And among the web sites that comprise the Keynote Business 40 Internet Performance Index, Apache server software is more popular than Microsoft's. 9.ÿ Internet performance improves substantially during the day on holiday periods such as Christmas and Thanksgiving. We believe that's because users spend time on other activities instead of surfing the Net from home or office. 10.ÿ Network engineers at backbone providers tend to focus on optimizing traffic flow within their own networks. They tend to de-emphasize or ignore connectivity and end-to-end response time to users on other networks. The Internet, however, is an interconnection of many backbones and private networks, with the result that users rarely access web sites that are directly connected to the same backbone that they are. ÿ For feedback or comments, please send email to marketing@keynote.com.
