本研究针对Web服务器的重尾特性，采用主动测量方法对Web服务器进行评价实验研究。我们的实验得出了三个结论：第一，它已被证明，总传输时间不仅是由文件大小，但也由第一次数据传输时间占主导地位。这意味着Web数据传输具有重尾特性的鲁棒性。其次，我们论证了如果服务器在初始数据传输阶段有一个重负载，发现服务器的性能很少有稳定的小方差。第三，Web服务器的性能评价指标的收敛性进行了研究。
In this research, we focused on the heavy-tailed property on Web servers, and studied evaluation experiments by an active measurement method for Web servers. Our experiments have resulted in three conclusions; first, it has been shown that the total transmission time is dominated not only by the file size but also by first data transmission time. It implies Web data transmission has the robustness of heavy-tailed property. Second, we demonstrated that if servers have a heavy load on the initial data transmission phase, to find that the performance of server rarely have stable small variance. Third, the convergence property of performance evaluation measures of Web servers was examined.
