Performance of a scheduling algorithm depends heavily on the number and types of requests. Requests for disk service can be greatly influenced by the file-allocation method. The location of directories and index blocks is also important. Other considerations for scheduling may involve rotational latency (instead of simply seek distances) and operating system constraints, such as demand paging.
