Hi,
Performance behavior of BPM scenarios is determined by the actual process model and the number of executed process instances of a process.
The following are the determining factors for a particular process:
• Number of messages received by a process (influenced by use of correlations)
• Number of messages sent by a process
• Number of transformations within a process (influenced by processed message sizes)
In general, process steps that generate work items internally are relevant for process performance. Transformation steps (either for message split or merge) also include a mapping step and can be quite expensive. This should be taken into consideration during scenario design.
For an example of resource consumption, see the BPM scenario described in the XI sizing guide:
The inbound SOAP messages are handed over to the BPE, which triggers a two-step process consist-ing of message reception and sending. The processed messages are then sent to a receiver by using the SOAP channel; no mapping.
The SAPS value for this scenario, in which 10 kB messages are processed, is 1300 (processing one process instance each second). A simple XI proxy scenario, for example, requires 140 SAPS process-ing one message each second. This gives you an idea of the resource requirements using BPM.
