VxVM is optimally tuned for most configurations ranging from small systems to larger servers. When you can use tuning to increase performance on larger systems at the expense of a valuable resource (such as memory), VxVM is generally tuned to run on the smallest supported configuration. You must perform any tuning changes with care. Changes may adversely affect overall system performance or may even leave VxVM unusable.

You can tune the VxVM and DMP parameters using the vxvoltune and vxdmptune utilities.
