None A change from 4.8.2p01 to 4.8.3 or 4.9.0 causes slow down

I'm simulating the BG (radiocative decays of different isotopes) coming from the materials of the detector.

I have Geant 4.8.2p01 on one computer, and 4.8.3 and 4.9.0 on other machines.

When I run the same simulation program with different versions of Geant, I see the difference in speed (4.8.2p01 is definitely faster) and the proportional difference in the size of the output file (*.root). The output file from 4.8.3 and 4.9.0 is almost 1000 times larger than the one I get from G4 4.8.2p01.

I'm trying to go through the list of changes made with the release of 4.8.3 version, but still haven't found anything.

May be anybody has an idea what could be the cause of such a difference in computational time, and, what is even more strange, in the size of the output root-file?
