Il lavoro presentato ha evidenziato come molto spesso le risorse hardware a disposizione non vengono sfruttate al massimo delle loro possibilit `a. Il principale collo di bottiglia risulta essere il sistema di I/O dei pacchetti, anche se un’architettura del software poco oculata `e in grado di ridurre drasticamente le prestazioni dell’intero sistema, a prescindere dal gestore di I/O di pacchetti utilizzato. In particolare la libreria per la gestione veloce di pacchetti di I/O netmap `e stata integrata in due software di rete abbastanza diffusi, Click e OpenvSwitch, riuscendo ad ottenere un incremento delle prestazioni da 4 a 10 volte maggiore rispetto al software originale.
