You could try adding/tweaking HZ to 1000/2000 in
kernel and add kern.polling.enable=1 to
/etc/sysctl.conf.

Try adding:
kern.ipc.somaxconn=2048
kern.maxfiles=65536
net.isr.enable=1
to /etc/sysctl.conf as well. net.isr.enable gave
better network-performance on a 5.3 RC3 nfs-server and
lower cpu-usage.
HTH.
