Description Viktor Lapitski 2007-02-21 09:11:34 UTC 
placeholder issue just for recordkeeping
Comment 1 Viktor Lapitski 2007-02-21 09:20:08 UTC 
the opening of a diagram consists roughly speaking of 2 parts:
1. independent of number of objects (ie. small diagram opening time)
2. and one that is clearly grows along with the number of objects on diagram

This issue is about part 2. 

The measurements before for a diagram with about 140 objects 
(classes and interfaces from UML sources
uml/core/src/org/netbeans/modules/uml/core/metamodel/core/foundation package):
1st opening - 40 sec.
2nd - 36 sec.

After the fix:
1st - 7-8 sec.
2nd 3-4 sec.

verified in build 070222. Yes, this is a huge performance improvement in opening
large diagram.
