COV Summary

Shown below are the average transfer times and the coefficients of variation (COV) for each of the elizas.  The COV is defined as the standard deviation of a distribution divided by the mean of the distribution.  In general a larger average transfer transfer time or COV is indicative of a volume's I/O performance varying due to heavy loads at times.
