Subject:   FreeBSD-11.0-CURRENT on ARM: performance and load average

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.
