I though I would provide an update on the case that I opened with Progress. They have been able to recreate the issue with the following results as logged by the support engineer. After enabling Tomcat DEBUG logging on ALL classes and sub-components I could identify com.progress.O4gl.Broker.readMsg() as the method responsible for the performance drop in the 4-core environment: side-by-side log comparison: ** Bottleneck 1 ** * 4 core PASOE environment * 06:58:59.252/636957 [catalina-exec-7] DEBUG com.progress.appserv.Timing - WRITEAGENTREQUEST(m0-TY9s3TneYLHQHq7ozeQ,SESSION ) RQID 06:58:59.252/636957 [catalina-exec-7] DEBUG com.progress.O4gl.Broker - readMsg() 06:58:59.366/637071 [catalina-exec-7] DEBUG com.progress.O4gl.Broker - readubhdr > 114ms ** versus1 core PASOE environment ** 06:09:03.533/1129666 [catalina-exec-9] DEBUG com.progress.appserv.Timing - WRITEAGENTREQUEST(STmp59lfS1WP2qqi5rgZAw,SESSION ) RQID 06:09:03.534/1129667 [catalina-exec-9] DEBUG com.progress.O4gl.Broker - readMsg() 06:09:03.545/1129678 [catalina-exec-9] DEBUG com.progress.O4gl.Broker - readubhdr > 11 ms ** Bottleneck 2 ** * 4 core PASOE environment * 06:58:59.383/637088 [catalina-exec-8] DEBUG com.progress.appserv.Timing - WRITEAGENTREQUEST(m0-TY9s3TneYLHQHq7ozeQ,SESSION ) RQID 06:58:59.383/637088 [catalina-exec-8] DEBUG com.progress.O4gl.Broker - readMsg() 06:58:59.959/637664 [catalina-exec-8] DEBUG com.progress.O4gl.Broker - readubhdr > 576 ms * versus1 core PASOE environment * 06:09:03.585/1129718 [catalina-exec-10] DEBUG com.progress.appserv.Timing - WRITEAGENTREQUEST(STmp59lfS1WP2qqi5rgZAw,SESSION ) RQID 06:09:03.585/1129718 [catalina-exec-10] DEBUG com.progress.O4gl.Broker - readMsg() 06:09:03.741/1129874 [catalina-exec-10] DEBUG com.progress.O4gl.Broker - readubhdr > 156ms They are still trying to rule out if it is a JVM issue but I doubt that that is the case since the same version of JDK running on Windows performs as expected.
