“B2B New Order Request” Workload Description: This workload is driven by a program that runs on a client work station that simulates multiple Web users. These simulated users send in cXML “New Order Request” transactions to the System i server by issuing an HTTP post which includes the cXML New Order Request file as the body of the message. Besides the Connect for iSeries product, other files and back-end application code exist to complete this transaction flow. For this workload, XML validation was disabled for both requests and response flows. The intention of this workload is to drive the server with a heavy load and to quantify the performance of Connect for iSeries.

Measurement Results: One of the main focal points was to evaluate and compare the differences between the back-end application connector types. The five connector types compared were the Java, JDBC, MQ Series, Data Queue, and PCML connectors. The graphs below illustrates the relative capacities for each of the connector types.
