Stuart Douglas created JBTM-1907: ------------------------------------ Summary: com.arjuna.ats.internal.arjuna.utils.UuidProcessId.getpid is slow Key: JBTM-1907 URL: https://issues.jboss.org/browse/JBTM-1907 Project: JBoss Transaction Manager Issue Type: Bug Security Level: Public (Everyone can see) Affects Versions: 5.0.0.M4 Reporter: Stuart Douglas Assignee: Tom Jenkinson the getPid() method uses a synchronized block that is hit on every call, which can causes a lot of unnecessary contention. I'm not sure why the pid cannot just be initialized in the constructor? Or failing that a volatile var + double checked locking would be faster. -- This message is automatically generated by JIRA.
