After installing geant4.10.06p02, I realized that it takes much more time to process e.g. 100 events with my prefered benchmark application (studying muon production by 18 GeV electron beam on copper dump) respect to geant4.10.06p01.
In particular, running both versions with “time”, I get for geant4.10.06p02
and for geant4.10.06p01 I get
So while the sys-time is more or less comparable, user time is much larger for geant4.10.06p02.
I tried on several computers, also with different compiler versions, but the result is always like this.
What could be the reason for this slow-down?
