***********************
Direct directory-to-directory mirror within current worksystem(no internet involved)

Traditional filecopier - 0m0.422s
VRangesync - 0m0.114s


VRangesync 0m0.114s timing prove itself as the ideal file copier choice for sync within current worksystem


***********************
Direct directory-to-directory mirror over the wire (internet involved)

Traditional filecopier(ssh) - 0m10.363s
VRangesync(ssh) - 0m10.155s
