Problema distribuzione non uniforme IP
L'IP che termina con .21 viene sempre assegnato alla coda "sbagliata".
Vedi 
Inoltre se salgo sopra i 31kHZ è sempre il .21 ad essere presente nella ricezione da 2 pacchetti
Risultati 16 core
a 449 kHz solo il core 15, quello che riceve il IP .21 di troppo non ce la fa, con 16 code. a 450 kHz cominciano a cedere anche gli altri
