You can take a number of actions to improve performance
for an IBM® Tivoli® Storage Manager server
that is running in a Windows environment.
Procedure
The following actions can help improve performance:
- Disable NTFS file compression on disk volumes. Because
of the potential for performance degradation, do not use NTFS file
compression on disk volumes that are used by the Tivoli Storage
Manager server.
- Use the shared memory communication method when you are
using a local client. For optimal backup and restore performance when
you are using a local client on a Windows system,
use the shared memory communication method. The method is used by
including the COMMMETHOD option set to SHAREDMEM in
the server options file and in the client options file.
- Use the VMXNET 3 network adapter type when the Tivoli Storage
Manager server is
in a VMware guest environment. Provide all disks that are used for
the server database, log file, and storage as mapped raw LUNs rather
than using virtual disks in a VMware datastore.
- Additional actions can affect Tivoli Storage
Manager client and
server performance.
- Windows 8 Defender can
significantly degrade Tivoli Storage
Manager backup and
restore throughput, especially for smaller files. To improve backup
and restore performance on Windows 8,
which might increase the security risk to the system, use one of the
following methods:
- Disable Windows 8 Defender.
Click Start > Administrative Tools > Computer
Management > Services and Applications > Services.
Locate Windows 8 Defender
in the list of services. Right-click Windows Defender and
then select Properties. Change the Startup
Type attribute to Disabled.
- Without disabling Windows 8
Defender Service, exclude a specific drive that has backup or restore
errors. Use this method when there are multiple logical drives on
the system. Excluding a drive is less of a security risk than disabling Windows 8 Defender Service.
- Antivirus software can negatively affect backup performance.
- Disable or do not install unused services.
- Disable or do not install unused network protocols.
- Give preference to background application performance.
- Avoid screen savers.
- Ensure that the paging file is not fragmented.
- Ensure that any device driver is current, especially for new hardware.
