On a classic page, the Content Query web part is a tool for finding and displaying information. However, this web part can affect page performance. Consequently, we are adding an alert for classic publishing portals that use Content Query web parts.When this will happen
- We’ll be gradually rolling this out in late April.
- The rollout will be complete in late May.
How this will affect your organization
This affects only classic publishing portals when the Content Query web part is affecting page performance.
In that case, a user who has edit rights may see a dismissible slow performance banner when the page is in draft mode.
The banner will automatically display under either of these conditions:
- If it takes >500 ms for the Content Query web part to load, or
- If the webpart is set up to be cross-list, i.e. selected the source “show items from all sites in this site collection” or “show items from the following site and all subsites”
