800xa, Opening functional diagram takes long time
After upgrade from 5.0 SP2 Rev C to rev E, we are experiencing some functional diagrams are taking extremely long time to open the first time they are opened - 38minutes. Message "inserting component *tagname* goes throug all the objects in diagram. The second time, they open within 1-2 minutes.
Also, when looking at the Audit Trail, there are a lot of entries for 'Aspect "Function" modified', the first time the diagram is opened.
These are very big diagrams, 39 pages.
I don't know how to improve that. I could only tell you that we had also a lot of problems regarding the performance of Function Designer in all versions of 5.0 (so your problem seems "normal" to me). To avoid this problem in future I recommend to create smaller diagrams.
I believe the initial delay is due to corrections made.
Previously, function diagrams could consume large amounts of space in the aspect directory - eventually it would lead to memory problems in the workplace and/or aspect directory service during heavy engineering or export/import.
To counter the problem, the memory handling has been improved - I also believe the function diagram data is now compressed/decompressed when stored/retrieved in the aspect directory.
After upgrading, old diagrams will be "converted" to the new and more efficient version upon first opening. I believe this is the reason for the delay.
Please read about the improvements in the release notes, e.g. product issue 800xAENS-OL-5024-017.
