The calibration coefficient is calculated by by generating a series of random 
numbers and then sorting them. Admittedly, such operations are not directly 
related to logging but they nonetheless give a rough estimate of the host CPU's 
power.

There are many more performance tests in logback so such failures are likelier 
to occur in that project. Nevertheless, if such a failure reoccurs, do not 
hesitate to report it on this list, so we can take corrective measures.
