CSWP group cache is available on-premises as well
Hi,
In March 2014 we announced a new group cache for the Content Search Web Part (CSWP) in SharePoint Online. Since then we've seen a steady rise in the usage of the CSWP in SharePoint Online, both with and without this cache configured.
We've also seen that this cache does fit its purpose: quickly returning the same results to many users in a company in high-load situations for Intranets. So, if you are developing an Intranet solution with SharePoint online, consider using the CSWP with the group cache.
Customers with on-premises SharePoint Intranets have told us that they too want this option. So, now that the feature has had some bake-time in SharePoint online we've just checked it in for on-premises usage as well .
So, the CSWP group cache is part of the SharePoint 2013 September 2014 Cumulative Update (CU). (download link)
As before, this feature works with AD groups and claims, not SharePoint groups.
Enjoy,
