Desired value for disk sorts is as close to zero as possible. Try quering
mutiple time and observe result. If you get sorts(disk) in high, try
increasing sort_area_size. But, make sure that adding additional size does
not interfere with the real memory into virtual memoery on disk. If real
memory is using virual memory, will impact on your perfomance. You can try
combination with SORT_AREA_RETAINED_SIZE parameter with combination with
SORT_AREA_SIZE.
