Figure 1: BFC filter processing time for accepted events
Note an extra peaks around 23/33/43 seconds for the QCD sample
(they also present but less pronounced in gamma-jet sample)
I found that these are processing times needed for the first accepted by filter events
(not always the time for the first processed event and depends on filter acceptance rate).
Processing is much longer due to time needed to initiaize additional stuff in bfc makers
and it is ignored in the total cpu time estimate

2nd row: bfc time for accepted events per partonic pt bin
3rd row: bfc time for rejected events per partonic pt bin
