Looks like the slowest is this:
(03.092360) cg: adding cgroup /proc/self/fd/32/lxc/u1
(03.104262) cg: adding cgroup /proc/self/fd/32/lxc/u1
(03.120432) cg: adding cgroup /proc/self/fd/32/lxc/u1
(03.140747) cg: adding cgroup /proc/self/fd/32/lxc/u1
(03.152882) cg: adding cgroup /proc/self/fd/32/lxc/u1
(03.172275) cg: adding cgroup /proc/self/fd/32/lxc/u1
(03.192472) cg: adding cgroup /proc/self/fd/32/lxc/u1
(03.204734) cg: adding cgroup /proc/self/fd/32/lxc/u1
(03.232432) cg: adding cgroup /proc/self/fd/32/lxc/u1
(03.248411) cg: adding cgroup /proc/self/fd/32/lxc/u1
(03.272400) cg: adding cgroup /proc/self/fd/32/lxc/u1

for each process "adding cgroup" eats totaly ~200 msec.
16 times * 200msec, AFAICS.
