Question Performance of geant4.9.5.p01 compared to geant4.9.4.p01 

Forum: Installation and Configuration
Date: 13 Jul, 2012
From: vivek singh <vivek singh>

Previously I had geant4.9.4.p01 running on a machine with following configuration 
**********************************
OS- Fedora Release 10 64bit 
Kernel Linux 2.6.27.41-170.2.117.fc10.i686.PAE
GNOME 2.24.3
Hardware : 
Memory 7.9GB
Processor Intel(R) Core (TM)2 Quad CPU Q9550@2.83GHz
**********************************

In this configuration when I run example 'TestEm4' for 1000000 events it hardly took 1 minutes to process it. 

However I recently installed geant4.9.5.p01 using cmake on another machine with following configuration 
**********************************
OS- Ubuntu 12.04 64bit
Kernel Linux 3.2.0-27-generic
GNOME 3.4.1
Hardware : 
Memory 7.8GB
Processor Intel(R) Core(TM) i5 CPU 750@2.67GHzx4
**********************************

This time the same example 'TestEm4' took nearly 5minutes to process 1000000 events.

Suspecting it has got something to do with Ubuntu I installed geant4.9.5.p01 (using cmake) on another system with following configuration 

**********************************
OS- Scientific Linux 6.2 64bit
Kernel Linux 2.6.32-220.23.1.el6:x86_64
GNOME 2.28.2
Hardware : 
Memory 7.7GB
Processor Intel(R) Core(TM) i7-2600K CPU@3.40GHz x 7
**********************************
The problem is still there, this machine also takes around 5 minutes to run 1000000 events for 'TestEm4'. 

Can someone help me out of this as to why this is happening, is it because of the version change of geant4 (which should not happen) or is it because of running it on 64bit machine? Does the performance get affected because of this?
