Performance improvement: Find a way to reduce number of org.jbpm.bpel.graph.def.CompositeActivity.findVariable() calls ---------------------------------------------------------------------------------------------------------------------- Key: BPEL-311 URL: https://jira.jboss.org/jira/browse/BPEL-311 Project: jBPM BPEL Issue Type: Task Security Level: Public (Everyone can see) Components: Engine Affects Versions: jBPM BPEL 1.1.1 Reporter: Aleksander Adamowski Assignee: Alejandro Guizar According to our profiling data, during a single invocation of a relatively simple business process (cannot post it here for confidentiality reasons), jBPM-BPEL performs an unreasonable number of findVariable() calls. Using JProfiler, we've recorded almost 150000 findVariable() calls for a single process execution (the process definition contains only 31 bpws:variable elements collectively). I suspect that there's some algorithm which runs in exponential time with respect to the number of variables or activities. Maybe adding some form of variable caching could enable dramatic performance improvements? -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
