Unfortunately, the good news didn't last, altought the performance is much
better it's still not enough to process the whole traffic, it seems to me
that it doesn't take advantage of the multicore from my CPU, using a single
CPU each time. Never more than one simultaneously.
Can that be improved?
$ ps -p 15139 -L -o pid,tid,psr,pcpu
PID TID PSR %CPU

PID TID PSR %CPU
