Question:

When working with reports 2.5 it is very slow (between 7 and 10 seconds) to
move a field in the layout editor. This only seems to occur with large reports
which have many objects in the layout editor.

Answer:

First of all, as noted, the slow response when moving objects in the layout
editor should only be an issue when working with a large reports that contain
many layout objects. For the majority of reports this should not be an issue.

The following can be done to improve performance in the layout editor when
moving or modifying objects:

1)Turn off VIEW BY STRUCTURE in the Navigator Options under the Layout tab
  or if you are using Reports 2.5.3+ you can iconify the Object Navigator
2)Turn off Confine Mode.

By doing the above 2 steps an improvement in performance should be seen when
moving/modifying ojbects in the layout structure.  Note that great care should
now be taken, since Confine Mode is now turned off, and as objects are moved
around around it is easy to disrupt the integrity of the report layout. Make
sure to switch back to Confine Mode when editing is complete.

Why would these changes help?

With VIEW BY STRUCTURE off and Confine Mode off, Reports no longer needs to
verify whether each and every change made in the layout editor is a valid and
legal operation (i.e. when an object is moved, does it remain within its
parent/enclosing object). That is why extra care must be taken when modifying
objects in order to retain the integrity of the report layout.

Development are investigating these performance problem when moving or
modifying layout objects.
