Either way it would be the same (the other way is directly running scenario binary from ./build folder). Running with ./waf --run just has overhead in the beginning of the simulation, as it checks that the latest code is compiled. It has no effect on later simulation.</div><div><br class=""></div><div>---</div><div>Alex</div><div><br class=""></div><br class=""><blockquote type="cite" class=""><div class="">
