Question How to decrease the time used per event of optical process of plastical scintillation?

Hi,All :

   I am a beginners of Geant4, and now I am simulating a optical process of
plastical scintillation .
   The volume I  used is ( from outer to inner ) PAPER , air _empty , ,
Scintillation,  groove,  WLS.      
  Some properties I set are :
  (1) The REF  of paper is 0.985 , ;
 (2) Scintillation:  
      myMPT1->AddConstProperty("SCINTILLATIONYIELD",8000./MeV);
      myMPT1->AddConstProperty("RESOLUTIONSCALE",1.0);
      myMPT1->AddConstProperty("FASTTIMECONSTANT", 2.*ns);
      myMPT1->AddConstProperty("YIELDRATIO",1.0);
  The number of  Photon.Eletrons which was collected by PMT is about 60, buut
the time I used is about 1 minute  per event. The reason maybe come from the
reflection of phontons in the scintillation. So how can I improve my programe
to decrease the time used per event?
  Can anyone give me advice for the this  problem?  Thanks  in advance .

Best
    Wish
