That's an interesting observation - but (viewed from the outside) I would be a little suspicious that the normal distribution was an artifact of the data generation mechanism and the test mechanism.

I ran last week a couple of TPC load with 300 and 420 users then I used both transaction per second and logical reads per second metric and both showed normal data distribution and that is why I have doubts of how to use queueing theory in Oracle.
From your paper was you able to predict the change from v1 to x2 without run the actual test? Then run the test and validate the prediction?
