TPC-W: a benchmark for e-commerce

Benchmarking Models and Tools for Distributed Web-Server Systems

“…The TPC-W benchmark specification (note that it is not a tool) defines the details of the Web services and content at the site and the workload offered by clients [26,41]. It specifies a database structure oriented to e-commerce transactions for an online bookstore together with its Web interface.…”

“…The TPC-W benchmark specification requires that client requests be issued by a given number of "emulated browsers", which remains constant throughout the experiment [26,41]. The number of clients is obtained as a function of the database table size and appropriate scaling factors.…”

“…The TPC-W benchmark specification defines the collection of the Web Interaction response time (WIRT), which is the time interval occurring between the sending of the first byte of a client request that starts a Web interaction and the retrieval of the last byte in the last response of the same Web interaction [26,41]. This is necessary to compute the final metric that is, the throughput of Web interactions per second.…”

Sensitivity of software usage to changes in the operational profile

“…In this section we analyze the sensitivity of a software usage in a typical e-commerce application adopted from [17]. In the e-commerce applications users interact with the Web sites through sessions that consist of consecutive request to execute e-business functions (search, add to cart, Table 2.…”

“…Perturbation analysis of the hypothetical example pay and so on) during a single visit to the site. In [17], the user's navigation pattern within a session is captured by so called Customer Behavior Model Graph (CBMG). The Customer Behavior Model Graph describes how the users navigate through the site, which functions they use, and the frequency of transitions from one function to another function.…”
