Disabling Lagging List v3

[janiceg]

When moving from List v2 to List v3, you might experience a slower load time compared to List v2. This issue most often occurs:

• With a high number of records
• For list layouts displaying several columns
• If using complex queries

The processing is a bit slower due to more client-side processing.

What to do if you have performance issues with List v3

Consider using lists with fewer records — 20 at the most — to make the load time speedier. If this issue is so prevalent that you feel you need to disable List v3, you can do so either on specific lists or across the instance.

• To disable List v3 on specific lists:

  1. Ensure that you have the role of personalize_control.
  2. Navigate to the list for which you want to disable List v3.
  3. Right-click the list title menu icon and choose Configure > List Control.
  4. In the List Control form, select the Disable List v3 checkbox and click Update.
     

     Note: When you want to re-enable List v3, navigate to System UI > List Control and find your name in the list. Select it and clear the Disable List v3 checkbox.

• To disable List v3 across the instance:

  1. Ensure you have the admin role.
  2. Navigate to System Properties > List v3.
  3. Locate the property called Enable List v3 (glide.ui.list_v3.enable).
     
  4. Clear the check box and click Save.
