REF: PG 3 MARCH/APRIL 2000
DBAs can set specific level of running statspack. Level 0 & Level 5 does not impact resource usage that much so that you notice the difference. But Oracle warns not to run Level 10 cause it is marked as resource intensive.
Level 10 Statspack collects all statistics from level 0 and level 5 as well as child-latch information.
Level 5 is the default.
Hope this helps.
