Engine runs process instances in serie instead of in parallel
-------------------------------------------------------------
Key: BPEL-282
URL: http://jira.jboss.com/jira/browse/BPEL-282
Project: JBoss jBPM BPEL
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: Engine
Affects Versions: jBPM BPEL 1.1 beta 3
Environment: RHEL
Reporter: Santiago Erquicia
Assigned To: Alejandro Guizar
We are stress testing a BPEL process and we found out that the engine runs all the requests it receives in serie. That means that if there are two or more concurrent users of the system, one has to wait till the first process instance stops at some point (wait state) so the other request can be processed.
On our test environment, we are calling a web service which is also calling another web service. The are connection problems with the second one, so from time to time the web service just times out. This means that a concurrent user has to wait for that time out, and whatever is left of that process instance, in order to be processed.
On our JMeter test, the throughput keeps stable even if there number of request is bigger than the throughput of the BPEL engine. The result is that the time for response of each process request increases indefinitely if the usage is bigger than the throughput. This obviously doesn't scale at all for the processing requirement we are considering.
