A well-performing intranet is essential for employee productivity and engagement. However, as your intranet grows in content and users, you may start to experience slow page load times and other performance issues.

In this blog post, we will discuss some effective strategies for improving page performance in your SharePoint intranet. By implementing these tips, you can ensure that your intranet is a fast and responsive resource for all of your employees.

1. Use SharePoint Diagnostic Tools

   SharePoint includes a number of diagnostic tools that can help you to identify and resolve performance issues. These tools can help you to identify slow-loading pages, optimize web parts, and troubleshoot other performance problems.

2. Optimize Images

   Images are often the largest contributors to slow page load times. To optimize images for your intranet, follow these guidelines:

   Install @microsoft/sp-image-helper to reduce the image size.

   Usage

   import { ImageHelper } from "@microsoft/sp-image-helper";
   <img
     className="top-info__banner-img"
     src={
          ImageHelper.convertToImageUrl({
          sourceUrl: encodeURI("ImageUrl"),
          width: 450, //change image width as per your need
      })}
     alt=""
   />

3. Use Pagination and reduce unnecessary API calls

   Pagination is a technique used in API design to retrieve large datasets in a structured and manageable manner. When an API endpoint returns a large amount of data, pagination allows the data to be divided into smaller, more manageable chunks or pages.

   Benefits of using pagination in API calls:

   Reduced response size, Improved performance, Enhanced user experience

4. Remove unnecessary imports

   Removing unnecessary imports can enhance code efficiency and reduce memory usage.

5. Implement a Content Delivery Network (CDN)

   A CDN is a network of servers that distributes content across multiple locations. This can help to improve page load times for users who are located far from your intranet server.

6. Minimize the Use of Custom Scripts and CSS

   Custom scripts and CSS can add functionality and style to your intranet. However, too much custom code can slow down page load times. To minimize the use of custom scripts and CSS, follow these tips:

   • Minify and bundle custom code: Minification removes unnecessary whitespace and comments from code, while bundling combines multiple files into a single file.
   • Use a CDN to serve custom code: This can help to improve performance by caching custom code on edge servers.

By following these tips, you can improve the performance of your SharePoint intranet and make it a more productive and engaging resource for your employees.
