Additional locking guidelines

These locking guidelines can help reduce lock contention and speed performance:

Also, other tuning efforts can help reduce lock contention. For example, if a process holds locks on a page, and must perform a physical I/O to read an additional page, it holds the lock much longer than it would have if the additional page had already been in cache.

Better cache utilization or using large I/O can reduce lock contention in this case. Other tuning efforts that can pay off in reduced lock contention are improved indexing and good distribution of physical I/O across disks.
