Message: Hi,

from the quote that you posted (next time please provide exact url to the text you're reading) I would speculate that 10ms is simply a unit of measurement.

If operation (call end - call start) is less than 10ms, Oracle will add 0ms to the total amount. Imagine that you execute 100.000 calls, each call is taking 9ms of CPU. In reality you spent 15 minutes on CPU, but the Oracle statistics will tell you 0.

Regards,
Ales
