Here are some tests I have done at 256kb:
Line From-to Medium 8000 octet 1000 octet 32 octet
speed ping ping ping
in seconds in seconds in seconds
----- ------------- ---------- ---------- ---------- ----------
256kb Israel-Israel fiber .524 .068 .008
256kb Israel-Israel FR, CIR=0 .628 .144 .016
256kb Israel-USA satellite 1.096 .640 .572
256kb Israel-Europe fiber .576 .116 .052
For 32 octets and 100ms - that is twice the rate we get with
a fiber link from Tel-Aviv to Geneva - a few thousand miles.
