#To exectute this you need mongo filesystem utility.
#Run this inside the mongo directory.
#mongo utility can be found in www.namesys.com/benchmarks/mongo-xxx.tgz
#Description-this script tests the mongo utility which actulally give the time ie cpu time
#Real time etc on reiserfile system and jfs filesystem.
