Hi,
thanks for your statements, especially for kernel module (which was puzzling me).
we found out that most of the CPU load caused by batman comes from sending packets. Thats why we experimented to combine our daemon with a kernel modul in order to reduce the load. Unfortunately, we found out that the current modul design is not suitable to achieve this goal. It would be neccessary to move all the important routing code into the modul to see measurable effects. For this reason the modul probably wont be included in the coming release. If you are interested in our ideas just have a look into trunk/batman/linux/modules. There you will find another modul (mod_batgat) which will be included in the next release. It will help to reduce the load caused by the UDP tunnels on the internet gateways. There is still some polishing to be done and it must be ported to linux 2.4 before we can offer packages for it.
Reagrds, Marek
