I am using geant4-09-05-patch-02. I have a plastic scintillator implementation which has scintillation yield 8400/MeV. I get sometimes several tens of thousands of optical photons in an event in my scintillator and in such a case subsequently the Geant4 runs are extremely slow...(~several seconds per event, while previously I had around 100 times faster event rate). I tried to find the reason for it, I first tried my main guesses: I removed any step limiters I have, I turned off the I/O writing to my output root file - none of them improved the speed.
Following example, in my Physics List I specify the process as:
G4OpticalPhysics* opticalPhysics = new G4OpticalPhysics(); fPList->RegisterPhysics( opticalPhysics );
Is there any other parameter that might speed up the code? Perhaps some additional/coarser step limits can be configured for these guys? Or other suggestions how to speed up the optical photon processsing in Geant?
