The standard ping program of Windows 9x, NT and 2000 calculates somewhat inaccurate timings. Windows XP does a better job. Due to the scheduling of the processes under Windows the timings are often different (because of the wakeup time necessary for the sleeping process). Using the localhost and the parameter -d 0, there is no delay between the ping, so the responses are faster because the program have a different scheduling (no sleep at all).
I guess Microsoft has realized the (relative) inaccuracy of the PING program and improved it in XP, where response times under 10ms (<10ms) are now reported accurately. So the fact that you see response times <1ms is simply related to improved software in XP.
there is a utility called tping which lets you ping hosts and displays response times in milliseconds below 10. Here is where you can download it (go to the bottom of the page and download tpoin1.09.zip file):
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
