Hello, I'm testing real time patch -rt12 on kernel 2.6.21.4. When I run netperf (netperf -H 192.168.188.207 -t UDP_STREAM -D 1 -I95,5 -l 500 -- -m 1024) on the server (with rt kernel) I obtain a load of ~48% on IRQ-20 (that is the hard irq related to my ethernet) but I have no load on softirq-net-rx. Is this a correct behaviour? Or I need to enable something on /proc /sys? In my opinion the HARD-IRQ executes too much..
