Multiple instances can have different values.

This parameter is applicable only in an Oracle IOServer instance, which runs out of an Oracle Grid Infrastructure home.

The default value should work in most cases. However, under heavy I/O load, there may be some delays associated with posting processes out of I/O waits. In this case, a slightly higher value than the default may be appropriate.
