Hello everyone, Recently, I encountered a problem with -CURRENT on an ARM board (cubieboard2 to be precise). The problem was that the load average was above 2. Including the fact that the board has 2 CPU cores, that's strange. Also, the network throughput was way too slow: from 3 kilobytes per second earlier to 20..50 about now. Here's a workaround for that: > sysctl kern.eventtimer.periodic=1 With that, the network performance increased while LA decreased to a decent 0.3..0.5. -- wbr, Maxim Filimonov che@bein.link
