By the way, my running machine is P-III 1GHz with i820 chip and
FreeBSD-4.0-RELEASE.
Is the length of time tick for this plathome invert of 1GHz?
(1/10^-9 [s])? or 10 [ms] (I think it is the time ticks for FreeBSD)?
RTT = (tp)->t_srtt >> (TCP_RTT_SHIFT - TCP_DELTA_SHIFT) shows
sometimes rapidly increase to 40 between ti0 gigabit link.
I think 40 * 10 [ms] is too longer for rtt, so I confused..
If there is some information, would you please like toteach ?
Thanks-
