Description

Hello,

I got a Timing printout at the end of the job with "Avg" greater than "Max", which does not look right.

Timing service should be reviewed and tested for correct behavior under SLF5 and SLF6. There are rumors that a behavior problem was found and fixed by CMS: this should be verified.

The behavior you observed resulted from an incorrect calculation of the mean, which is particularly noticeable when a small number of events is processed. The correct calculation is now used for the average.

Fixed with 82b0f90a8eda2936cf18e9e450a6419ad58a39da.
