SharePoint 2019-open site very slowly

Question

When I opened a site, the site just is loading, and take 1 min to show the content, too slow. Are there any suggestions to improve the performance?

Hi @Andy ,

1.If the local speed is slow, it is recommended that you monitor all server roles, the network, whether the CPU is overloaded, the allocated memory resources are too low, or just the underlying storage system is slow.

2.Page customization can hurt overall performance, you could limit page customization to only when absolutely necessary. Site collection and farm administrators can also choose to disable Designer, or use the Reset to Site Definition option to undo changes and revert to the original content if necessary.

1)If you have a lot of content aggregates, I suggest you could try removing them from the page and see if that improves. If you eliminate all possible causes and add them back at once, you can identify which features are the biggest problems and then look for solutions.

2)Most SharePoint pages contain links to supporting files, including JavaScript and style sheets, that take extra time to retrieve and execute. Change how SharePoint pages retrieve these files, loading linked files in the background while the rest of the page renders.

3)When deploying customizations to SharePoint, the entire content and codebase is stored in the database and retrieved each time the page is requested. Leaving poorly written code can overload the database and slow its performance, you need to test all custom solutions.

3.SharePoint object caching can significantly reduce the execution time of resource-intensive components (such as content query web parts). For example, frequently requested large objects (such as images and files) can be cached on disk for each web application to improve page delivery time.

4.Navigation depth should be limited, getting all the data to populate the navigation menu can be resource intensive on sites with deep hierarchies, customize the depth and level of each navigation menu by modifying the parameters of the various navigation controls in the master page.

5.You could also try a variety of browsers in your environment to see if it improves your site speed.
