osip报文的解析速度测试

在惊鸿一瞥中，发现osip_event.c文件测试解析osip报文的速度
非常值得我们参考，尤其是大数据解析的时候：
osip_event_t *
osip {
int kk;
int pstime1, pstime;
struct timespec tv1;
clock_get_time (CLOCK_REALTIME, &tv1);
pstime = ((tv1.tv_sec * 1000) + (tv1.tv_nsec / 1000000));
for (kk = 0; kk < 10000; kk++)
{
i = osip_message_init (&(se->sip));
if (osip_message_parse (se->sip, buf, length) == -1)
{
fprintf (stdout, "osip_message_parse retrun -1\n");
osip_message_free (se->sip);
} else
{ /* msg is parsed */
osip_message_free (se->sip);
}
}
clock_get_time (CLOCK_REALTIME, &tv1);
pstime1 = ((tv1.tv_sec * 1000) + (tv1.tv_nsec / 1000000));
fprintf (stdout, "CPU clock ticks for 10000 messages - T1: %i - T2: %i\n",
pstime1, pstime);
fprintf (stdout, "CPU time for 10000 messages - %d\n", (pstime1 - pstime));
}
osip_free (se);
return NULL;
