- From $ man nmap :

  Significant effort has been put into decent nmap performance for
  non-root users.  Unfortunately, many critical kernel  interfaces
  (such  as  raw sockets) require root privileges.  nmap should be run
  as root whenever possible (not setuid root, of course).


So yes, it's normal to get more and better results if you're running
nmap as root.
