Subject Stats: Node Creation Time is 20-40 seconds
Date Wed, 11 Apr 2007 23:42:14 GMT

The session.save() and node.checkin() statement are causing the delay.  

I started with a new repository on my PC and deleted/recreated the tables on
the iSeries.  

I am loading a simple hierarchy:
   Forms Node                                     (1x total to parent root)   
      PEPPA node                                  (1x total to parent Forms) 
         PEPPACAT Node                         (3x total to parent PEPPA) 
            PEPPASUB Node                      (3-5x for each parent
PEPPACAT)
               PEPPAJOB#### Node         (4x for for each parent PEPPASUB)

There are 3-5 user (String) properties for each node (Forms ->
PEPPAJOB####).


I printed a Date/Time for each node as it is created.  This is a partial
listing:

Node Creation Time is 20-40 seconds!!!


You mentioned using a bundle persistence manager.  How do I
download/install/configure it?  I am using WebSphere 5.1 (WDSc).  My current
settings/configurations are in a previous thread


Any help would be appreciated!

Thanks,

Skip
