To be honest (and embarassed), I have no clue. Maybe someone else
does. Alan?

Re: Did some extensive hipersocket testing/benchmarking.... need help
interpreting results.
I don't know if this high school dropout can handle this, but let me
try. I got me a hipersocket with an MTU of 57344 (on both ends), so:
For the biggie:
tux:~ # ping -f -A -c 100 -s 57308 10.2.32.3
PING 10.2.32.3 (10.2.32.3) 57308(57336) bytes of data.
--- 10.2.32.3 ping statistics ---
100 packets transmitted, 100 received, 0% packet loss, time 219ms
rtt min/avg/max/mdev = 0.596/0.757/1.602/0.194 ms, ipg/ewma 2.212/0.790
ms
I would have:
( 57308 + 20 + 8 + 8 ) * 100
---------------------------- = 151,503,302.5 or 144 MB/s
.757 * 100 / 1000 / 2
For the smallie:
tux:~ # ping -f -A -c 100 -s 16 10.2.32.3
PING 10.2.32.3 (10.2.32.3) 16(44) bytes of data.
--- 10.2.32.3 ping statistics ---
100 packets transmitted, 100 received, 0% packet loss, time 56ms
rtt min/avg/max/mdev = 0.100/0.158/0.483/0.062 ms, ipg/ewma 0.573/0.147
ms
I would have:
( 16 + 20 + 8 + 8 ) * 100
------------------------- = 650,000 or 634 KB/s
.160 * 100 / 1000 / 2
And for the comparative:
5734400 - 5200
-------------- = 154,634,278 or 147 MB/s
.03785 - .0008
I can live with that. What is the theoritical maximum for a
hipersocket?
