How to Fix SharePoint Custom Forms That Are Slow and Unresponsive

This article explains how to fix SharePoint custom forms that are slow and unresponsive, and provides some possible causes and solutions for this issue.

SharePoint custom forms are a great way to customize the user interface and functionality of your SharePoint lists and libraries. However, sometimes you may encounter a problem where your custom forms become extremely slow, often unresponsive, and take a long time to load or submit. This can affect the user experience and productivity of your SharePoint site. In this article, we will explain the possible causes of this issue, and provide some solutions to fix it.

How to Fix SharePoint Custom Forms That Are Slow and Unresponsive

Possible Causes of SharePoint Custom Forms Slowness

There are several factors that can contribute to the slowness of SharePoint custom forms, such as:

  • The size and complexity of the custom form. If your custom form has too many fields, controls, validations, or calculations, it may take longer to render and process the data.
  • The network latency and bandwidth. If your network connection is slow or unstable, it may affect the communication between your browser and the SharePoint server, resulting in delays or timeouts.
  • The browser compatibility and performance. If your browser is outdated, incompatible, or has too many extensions or add-ons, it may affect the rendering and functionality of your custom form.
  • The SharePoint server performance and configuration. If your SharePoint server is overloaded, misconfigured, or has insufficient resources, it may affect the response time and availability of your custom form.

Solutions to Fix SharePoint Custom Forms Slowness

Depending on the cause of the issue, you may need to apply different solutions to fix the slowness of your SharePoint custom forms. Here are some common solutions that you can try:

  • Optimize your custom form design. You can reduce the size and complexity of your custom form by removing unnecessary fields, controls, validations, or calculations; splitting your form into multiple pages or tabs; using cascading dropdowns or lookup fields to filter data; or using asynchronous calls or lazy loading techniques to load data on demand.
  • Optimize your network connection. You can improve your network connection by using a wired connection instead of wireless; closing other applications or tabs that consume bandwidth; or using a proxy server or a content delivery network (CDN) to reduce latency.
  • Optimize your browser settings. You can update your browser to the latest version; use a compatible browser that supports SharePoint features; clear your browser cache and cookies; disable or remove any extensions or add-ons that interfere with SharePoint; or use a different browser to test your custom form.
  • Optimize your SharePoint server performance and configuration. You can monitor and troubleshoot your SharePoint server performance by using tools such as Performance Monitor, ULS Viewer, Developer Dashboard, or Fiddler; adjust your SharePoint server settings such as throttling, caching, or load balancing; or scale up or out your SharePoint server resources.
