I am running the same test, but connecting twice on the remote machine (one connection by test instance). I am using exactly the same commands than during the others experiments. But, by using two SSH instances, the niceness will not be taken into account.

Can you check whether you have CONFIG_SCHED_AUTOGROUP enabled? If it is enabled, try running the test again with this option turned off. -Michi -- programing a layer 3+4 network protocol for mesh networks see http://michaelblizek.twilightparadox.com
