Mark,

Chuck Pence just posted a message about a V4R5 performance problem on the
comp.sys.ibm.as400.misc newsgroup.  There's a new PTF coming out, MF24874,
to correct it.  This is an excerpt from Chuck's message:

Per the APAR:
  PROBLEM CONCLUSION:                                          
  A coding error was causing an exception while writing out    
  journal entries.  ... successfully writes the journal entries.
  ...  This PTF corrects the coding error.

Can E3 tell you if the people with the problems were journalling their
files?  That would verify whether this is the same problem or not.

We have not upgraded, but have been "warned" by our purchasing software
vendor (E3) that some people have
had performance degradations after upgrading to V4R5 with their software.
A nightly run was taking 4-5 times longer then before the upgrade.
The letter did not mention model numbers, but we are on a 620.
Seeing how the software runs (they do not send any source code), my guess is
that data base access has been slowed somehow; their software is not the
quickest or the leanest that I have seen with it being common to having
20-25 files open for a simple purchase order run, and ridiculous file I/O
numbers.

We at least here are waiting for another month or two before upgrading from
V4R4 to V4R5.
