[OLSR-users] dot plugin

[Sven-Ola Tuecke]

Hi,

the freifunk-olsrd is compiled with the usual CFLAGS 
("-Wall -Wmissing-prototypes -Wstrict-prototypes -O2 -g"). Thomas Lopatic 
has pointed out, that extensive search through linear routing tables causes 
the high CPU load. The Freifunk-Firmware now starts without debug, so here 
in Berlin we have a load of 30% with a typical WRT54G (V2.0).

If the olsrd starts loosing routes: Are you shure, the dot-draw does not 
halt olsrd main thread execution during calculations? As far as I know, 
there are some issues with threading and plugins right now. One of the 
drawbacks with the dyn-gw-ping-enhancement also...

LG, Sven-Ola
