Description

When the item cloning feature is enabled on a solution, a user might experience performance issues. Basic user operations such as creating or loading items can be affected by this issue.

Note that the issue does not affect Sitecore CMS 7.2.5 and 7.2.6 versions.

Solution

To resolve the issue, consider one of the following options:

• Upgrade Sitecore XP instance to Sitecore XP 10.1.0.
• Download and install the hotfix compatible with the affected product version:
  
  • For Sitecore XP 10.0: SC Hotfix 450723-1.zip
  • For Sitecore XP 9.3 Initial Release: SC Hotfix 442883-2.zip
• Disable the item cloning feature:
  
  • To check if item clones are not used on a solution, see the following article: How to verify whether the item cloning feature is used.
  • To disable item clones, change the value of the following setting from "true" to "false":
    

    <setting name="ItemCloning.Enabled" value="false"/>

  Be aware that hotfixes were built for specific Sitecore XP versions, and must not be installed on other Sitecore XP versions or in combination with other hotfixes. In case any other hotfixes have already been installed on a certain Sitecore XP instance, send a request for a compatibility check to Sitecore Support.

  Note that the ZIP file contents need to be extracted to locate installation instructions and related files inside. The hotfixes must be installed on a CM instance and then synced with other instances using standard development practices.
