Issue description

One of our clients reported performance issues on the home page of their intranet, which includes several of our custom web parts as well as out-of-the-box web parts. The client created a support ticket with Microsoft, and the response indicated that the Page Diagnostics for SharePoint tool shows the page is exceeding the limits of requests to SharePoint APIs and Search APIs. The support team suggested that our web parts might be the cause of this issue.

However, we have developed these web parts following the SPFx best practices recommended by the Product Team and the community. To further investigate, we tested the Page Diagnostics tool on multiple scenarios and found that it shows failures even on pages with only nine out-of-the-box web parts.

Given this context, we would like to ask if the Product Team has considered the output of this tool in relation to the principles and modularity of SharePoint web parts and SPFx solutions. It seems that the tool's output might not align with the intended benefits of using SPFx web parts.

The screenshot shows the output of the tool on an out-of-the-box page with only 9 out-of-the-box web parts.

The web parts we used on this page are:

• 1x Image web part
• 1x News web part
• 1x quick links web part
• 3x Highlighted content web part
• 1x List web part
• 1x Sites web part
• 1x Events web part
