Hi,
We are experiencing a serious performance issue on SharePoint 2013 which seems to be related to an known issue in SharePoint 2010 and according to some technet posts, see links below, this is expected to be fixed in the upcoming SharePoint Server CU. Can you confirm if this is the case and when the CU is likely to be available for SharePoint Server 2013?
