Disabling I/O statistics collection

By default, Veritas Volume Manager collects I/O statistics on all objects in the configuration. This helps you tune different parameters that depend upon the environment and workload.

After the tuning is done, you may choose to disable I/O statistics collection because it improves I/O throughput.
