How to evaluate Site Performance in SharePoint using the Site Performance feature

Posted on December 21, 2023
SharePoint

If you built your sites/pages in SharePoint and your site is horribly slow, you might want to run some diagnostics using the Site Performance feature we now have available in SharePoint Online. In this article, I would like to describe the feature and explain what kind of good information it might give you.

What is SharePoint Site Performance Feature?

Site Performance feature is a new feature we have in modern SharePoint that allows you to evaluate the performance of your SharePoint pages. It checks the SharePoint pages for content that might slow down the page load times and performance.

Sites vs. Pages

It is essential to note that Site Performance, despite being called a Site Performance tool, actually evaluates pages located on the site. At the end of the day, it is the pages that contain the web parts embedded on the pages, so when you load a site, you actually load one of the pages located on the site. To understand the difference between sites and pages, please check out this post.

Who will benefit from the SharePoint Performance Site Feature?

In all honesty, if you are using SharePoint Out of the Box, you probably do not need to worry about this feature too much. If you only used an out-of-the-box functionality (web parts), your pages should load just fine. If they load slow, check your internet connection or ask your boss to buy you a new laptop. 😊. You might still get trivial reasons for slower page load (i.e., large images used, etc.). However, the Site Performance feature will greatly benefit users who have done some custom development and injected code or third-party web parts into the pages.

It advised that the Embed Web Part caused the page to be slower. Indeed, I had a few videos embedded on my SharePoint page. And while for most, I used File and Media Web Part, for one of the videos, I used Embed Web Part. So, this gave me the idea to change it to the File and Media Web Part to make my page faster.Site Performance in SharePoint
