[OLSR-users] High CPU utilization

Hello -
I've got some netgears that I'm running olsrd on and am running into
regularly 60-80% cpu utilization. This seems to have the negative effect of
causing a slowdown in performance (for obvious reasons).
Any ideas on how I can get this down? This is my conf file, and following
that my current mesh list as seen by a typical node:
#
# olsr.org OLSR daemon config file
#
# Lines starting with a # are discarded
#
# This file was shipped with olsrd 0.5.0-unoffical
#
# This file is an example of a typical
# configuration for a mostly static
# network(regarding mobility) using
# the LQ extention
# Debug level(0-9)
# If set to 0 the daemon runs in the background
DebugLevel 0
# Fisheye mechanism for TC messages 0=off, 1=on
LinkQualityFishEye 1
# Don't recalculate the Dijkstra-table for every incoming topology
# control packet. There is no need to recalculate the whole table
# if a minor change occured several hops away. Small CPUs will start
# to glow if you do this in a mesh of considerable size. Rather the table
# should be recalculated if a change occured in the neighborhood
# of this node. The first number is the number of hops. Nodes within
# this number of hops trigger a recalculation of the table. If the
# number is 0 no incoming topology control packet will trigger
# a recalculation of the table. The second number (floating point!)
# is the length ot the interval until the table is recalculated anyway.
LinkQualityDijkstraLimit 1 6.0
# IP version to use (4 or 6)
IpVersion 4
# Clear the screen each time the internal state changes
ClearScreen yes
# HNA IPv4 routes
# syntax: netaddr netmask
# Example Internet gateway:
# 0.0.0.0 0.0.0.0
Hna4
{
# Internet gateway:
# 0.0.0.0 0.0.0.0
# more entries can be added:
# 192.168.1.0 255.255.255.0
}
# HNA IPv6 routes
# syntax: netaddr prefix
# Example Internet gateway:
Hna6
{
# Internet gateway:
# :: 0
# more entries can be added:
# fec0:2200:106:: 48
}
# Should olsrd keep on running even if there are
# no interfaces available? This is a good idea
# for a PCMCIA/USB hotswap environment.
# "yes" OR "no"
AllowNoInt yes
# TOS(type of service) value for
# the IP header of control traffic.
# If not set it will default to 16
#TosValue 16
# The fixed willingness to use(0-7)
# If not set willingness will be calculated
# dynamically based on battery/power status
# if such information is available
#Willingness 4
# Allow processes like the GUI front-end
# to connect to the daemon.
