Optimizarea a fost realizat\u0103 prin inline manual pentru 2 func\u021bii. Se observ\u0103 c\u0103 func\u021bia timecounter_cyc2time() poate fi apelat\u0103 pentru fiecare pachet primit, deoarece protocoalele moderne necesit\u0103 \u00eenregistrarea timpului sosirii pachetului. Din cauza aceasta, pe un sistem \u00eempov\u0103rat, server<\/a> func\u021bia timecounter_cyc2time() poate fi apelat\u0103 de peste 100 de milioane de ori pe secund\u0103. <\/p>\n

Totu\u0219i, desf\u0103\u0219urarea manual\u0103 inline a func\u021biei a adus un c\u00e2\u0219tig semnificativ \u00een performan\u021b\u0103.
