hi. i've just been upgrading my package from geant4.3.2 to 4.4.0 which worked rather smooth and nicely. unfortunately there seem to be some differences between the two versions that i'm not aware of. running example N03 with 20000 incident particles (with all the visualization switched off!) seems to imply that 4.4.0 is about a factor of 2 slower than 3.2.0 (user: 36.9s - 85.0s; real 49.1s - 104.8s; sytem 1.6s - 1.8s). the same (about a factor of 3) is true for N02, though here might be some clue as to what causes it, i.e. the number of stored trajectories is at least a factor of 7 or so higher. apparently something is 'switched on' that wasn't in 4.3.2, but unfortunately i have know idea as to what that might be. thanx for you help frank
