you can affect the load-balancing with the speed-sliders.

these are relative values according the cpu speed calculated by the
openMosix kernel at each startup.

the result may be the same. I would lower the speed value on the node.
e.g. you have a slow system and you still want it to get some processes.
Just "make it faster" using the speed-sliders or "mosctl setpeed [n]".
Then openMosix will "think" that the node is faster and will migrate
processes to it. It is especially usefull if you have a cluster built from 
heterogenous hardware.
