I have seen some surreal results reported by some of the speed test sites
if you have a sufficiently fat pipe. Near as I could tell, every single hop was
gigE or better all the way, the speedtest site then tried to apply a correction
for the bottleneck it knew about on its local gigE nterface, and basically decided
that the *rest* of the path must be near-infinite speed. ;)
