Comment:
I'm afraid it is a false positive - you are sending/receiving packets for 21 s
(verbose_interval + 1) but calculate pps against 20 s (verbose_interval)
stall = 20
stall = 1
sent: 0, drops: 0, send rate: 0 pps, max send rate: 0 pps, rcv: 38703598, recv
rate: 988582 pps, max recv rate: 988582 pps
Try this:
#if 0
stall = (stall / ODP_TIME_SEC_IN_NS) + 1;
stall &= 0xFFFFFFFF;
printf("stall = %d\n", (unsigned int)stall);
sleep((unsigned int)stall);
#else
if (stall / ODP_TIME_SEC_IN_NS)
sleep(1);
else
usleep(stall / ODP_TIME_USEC_IN_NS);
#endif
With this change I can still see an increase on performance but with reasonable
value.
