Significant performance degradation might occur in live and history aggregation for Sitecore 10.0 rev. 004346 (Initial Release). The aggregation can be noticeably slow compared to the previous releases.
To resolve the issue, consider one of the following options:
Be aware that the hotfix was built for a specific Sitecore XP version, and must not be installed on other Sitecore XP versions or in combination with other hotfixes. In cases where other hotfixes have already been installed on a particular 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.
