Weird.  Using the -Ae flag doesn't make a difference in time for me,
nor does using sudo (this is testing it by hand, not from within
hobbit).  Still, it seems like you are doing better than we are.
I wonder if this is a Fedora-specific peculiararity?  I'll try
installing fping on my wimpy Arch Linux desktop box and seeing
if I can glean anything conclusive (although the difference
in hardware is going to make this difficult).

Thanks for sharing!
