HI Wolfgang,
It was the IXXAT PCI card currently plugged into my test PC but I
actually recommand the PEAK PCI card. It's also much cheaper, I guess.
Tomorrow I'm going to repeat the tests with this card ... stay tuned.
Clear. Thanks for the advice.
I will continue development on my laptop with the dongle for the time
being. It would be interesting to see what happens to the latency
after your proposed changes are in effect.
BTW, what are the latencies you measure on your system under load
(without RT-Socket-CAN).
Off the top of my head 25us average 30us to 35us max. I am not sure I am
"loading" the system though. How do I measure this load that is always
talked about?
While the latency test is running execute in other windows:
- while ls; do ls; done
- ping -f <remote-host>"
- dd if=/dev/zero of=/dev/null
and let it run for a few hours. And also search the file TROUBLESHOOTING
for "stress".
Wolfgang.
