Avoiding I/O Disk Contention

Disk contention occurs when multiple processes try to access the same physical disk simultaneously. Disk contention can be reduced, thereby increasing performance, by distributing the disk I/O more evenly over the available disks.




A large difference in the number of physical writes and reads between disks may indicate that a disk is being overburdened.
