Howdy!
Actually clock synchronization is quite tough job when one needs
sub-millisecond acuracy. Here's output of one host:

I'm not sure if you've looked into it, but there's another tool,
OWAMP, that can be used to measure delay, jitter and packet loss
unidirectionally ( http://www.internet2.edu/performance/owamp/ ). The
thing with unidirectional packet measurement is that the hosts need to
have their clocks we
Hi!
I tried to replicate your tests ... using 3G HSPA+, iperf 2.0.4 on
debian on internet side and jperf (iperf 2.0.2) on windows xp on dial-up
side.
I can see delay jitter reported by receiving side (in my case it's
around 7.5ms in average in either direction when pushing 1.8Mbps of
UDP),
