EA performance issues with IBDs

[jas11]

We're experiencing some significant performance issues in EA (v17.1.1714), specifically when working with Internal Block Diagrams (IBDs).

We have a fairly complex IBD containing around 20 properties. When the diagram is first opened, any changes made to it can take several minutes to save. Similar performance degradation occurs when enabling/disabling ports on properties or assigning flow properties to connectors within the diagram.

The issue only affects the initial save or the first port/connector operation. Subsequent saves and port/connector updates are performed in an acceptable timeframe. However, if the diagram remains open but inactive for a few minutes, or is closed and reopened, the performance issues return and the next operation is again very slow.

Our initial assumption was that the problem might be related to network or server performance, as we're using a Microsoft SQL Server repository. However, as a test, I created a local file-based repository containing the same model and observed similar behaviour. Performance was somewhat better than with SQL Server, but the issue was still present.

Has anyone experienced similar behaviour with IBDs, or are there any known causes or diagnostic steps we should investigate?

This is an issue related to complex diagrams. I analized that some time ago and as I remember the reason is, that it checks for whatever reason any item on the diagram and maybe even more if the element is locked. My solution: I avoid complex diagrams;). For IBD e.g. I have many under a complex block focusing on different aspects.
