For what its worth : This is what I get in a 1CPU 2GBRAM Vmware guest
VM thats running on my desktop. '/tmp' is a 'local' xfs lvm2 fs, and
'/mnt/glusterfs/0/' is a glusterfs mountpoint, where servernode and
clientnode are the same vm. Not blazingly fast as its a vm on a
desktop, but noticably slower than doing a comparable 'cp' on a
non-glusterfs mountpoint.
