Hi,
While looking in to the java APIs it seems that the method calls on the objects are also contacting the server.
eg .. WorkItem.inContainer();
or say ReadOnlyContainer.getString("firstName");
i believe that the object returned say a WorkItem object is just a handle and not an object with all the properties set. So each time i invoke a method on such an object the call is going to the workflow server. This seems to be a performance problem when i 've large number of workitems or a large datastructure.
Is my understanding correct ?

Also when i call WorkItem.inContainer() for a single user(and single workitem) it takes 50 milliseconds (say) . But if i call WorkItem.inContainer() for 10 users (single worikitem) it takes 500 milliseconds for each user.
is it an expected behaviour ?

The initial call to the object retrieves all of the "PRIMARY" attributes (see programming guide for list). The first reference to any SECONDAY attribute OR a .refresh() call on the object will get ALL of the Secondary attributes
