Hello,
my first mail to the list :)
I run a set of tests with netperf:
for i in 1 2 3 4 ; do netperf -H netserver -c -C -i 10 -P 0 -- -s 128k
-S 128k & done

So far, it seems that most tools show about the same numbers - beside the
DTrace script "nx.se", which output i just do not understand.
Shoudn´t "TCP_in" be number of bytes read from network?
Those numbers are by far too high!
For example, 1039588008 is 1,039,588,008 (one billion) ...
What shall that be?
Can anybody enlighten me about the results of "tcpstat.d"?
I am just not sure how to interprete the numbers - or if those results are comparable to other tools at all.
BTW, i created "tcpstat.d_10s" from "tcpstat.d" with changing "tick-1sec" to "tick-10sec".
But the numbers are the same for the original script!
Thank you very much!
