Cubieboard: load average above 2

Fri Sep 5 21:41:44 UTC 2014

Recently, I installed FreeBSD-current to my Cubieboard2:
root at cubie:~ # uname -a
FreeBSD cubie 11.0-CURRENT FreeBSD 11.0-CURRENT #2 r271182M: Sat Sep  6 
01:17:28 MSK 2014     root at quad:/usr/obj/arm.armv6/home/che/freebsd-
src/head/sys/CUBIEBOARD2  arm

And the system's load average keeps being above 2:
root at cubie:~ # uptime 
 8:31PM  up 19 mins, 1 user, load averages: 2.36, 1.89, 1.32

Everything is not really slow, but sometimes takes time.
What could be the problem here? What can I do with that?
