2. "Typically, this parameter should be set to the number of separate
drives comprising a RAID 0 stripe or RAID 1 mirror or any combination.
For RAID 5, it should be set to the number of drives excluding the
parity drive. However, the optimal value varies based on the
effectiveness of the RAID controller or software implementation, and
may require some experimentation."
3. "For more exotic systems, such as memory-based storage or a RAID
array which is limited by bus bandwidth, the correct value might be
the number of paths available instead; again, experimentation is
4. Insert comma after "However" in third sentence. Replace last
sentence with: "On these operating systems, setting
effective_io_concurrency to a value greater than 1 will incur some CPU
overhead without improving perforamance."
