Applies to:

PeopleSoft Enterprise PT PeopleTools - Version 8.52 to 8.54 [Release 8.4]
Information in this document applies to any platform.

Symptoms

Running Application Engine(AE) on PT 8.52

ACTUAL BEHAVIOR
---------------
TraceAE is set to 7 in command line or Process Definition or psprcs.cfg.

PeopleSoft ARPredict job when run creates a trace file of about ~400Mb in size.  When the trace file is written to a local disk drive the batch process completes in 30 seconds.
If the same test is run but targets the trace file to a directory located on an NFS file system, it will take 4 minutes 30 seconds to complete.

EXPECTED BEHAVIOR
-----------------------
The process should take same amount of time to complete when trace file location is in NFS file system or in local file system.

STEPS
-----------------------
The issue can be reproduced at will with the following steps:
1. Following PeopleCode was tested as part of the PeopleCode step in AEMINITEST

2. AEMINITEST was invoked from Process Scheduler and Command Line with
 TraceAE=7.

3. Use strace to  to verify No open/close calls to AET file.
