Performance is degraded if the Active Directory domain controller and file services are configured on the disk on which OpenText eDirectory is installed.
For better performance of OpenText Identity Manager on Windows, enable write caching on the disk as follows:
Right-click My Computer > Properties > Hardware > Device Manager > Disk drives.
Right-click the drive on which OpenText eDirectory/Identity Manager is installed and click Properties > Policies.
Select Enable write caching on the disk.
