TPC-W was a web server and database performance benchmark, proposed by

Transaction Processing Performance Council In online transaction processing (OLTP), information systems typically facilitate and manage transaction-oriented applications. This is contrasted with online analytical processing. The term "transaction" can have two different meanings, both of w ...

s) that the system under testing needed to show in the virtual shop. Standard also describes how random strings and random numbers must be generated. During testing, the server was visited by a growing number of web-bots, each simulating individual customer. The pause between web interactions from the single customer and the number of total pages each customer visits per session are random numbers that must follow asymmetric distribution, specified by the standard. The navigation pattern is defined by three transition tables that differ in accordance with the preferred plans of the user (shopping mix, browsing mix and ordering mix). The main measured parameter was WIPS, the number of web interactions per second that the system is capable to deliver. It was also possible to visit and actually use the virtual shop with the ordinary browser. The official TPC-W page in the past included performance comparisons, providing information, how well the virtual shop performs when implemented with various development platforms and running on various web servers and
