v4.5.0

Python Version

3.12

Steps to Reproduce

Create a Site.
Populate the Site with a large number of related objects:
- Devices: 1,248
- Locations: 1,079
- Prefixes: 4,358
- VLAN Groups: 1
- VLANs: 17
Update the Site’s Physical Address.
Submit/save the change.

Expected Behavior

For sites that have no related objects, applying changes completes in less than one second, suggesting approximately constant-time behavior. This should not materially change as the number of related objects increases.

In contrast, with a high volume of related objects, execution time appears to increase linearly, consistent with O(N) scaling, where N is proportional to (site + related objects).

Observed Behavior

A timeout occurs during the update.
