Maybe a newbie question here. Here are my findings on my server since it enters the cn zone:
At 30k QPS, dropped packets at ~100/s, bandwidth usage at 30~50Mbps, ntpd CPU ~10%;
At 80k QPS, dropped packets at ~1.5k/s, bandwidth usage at 80~90Mbps, ntpd CPU ~30%;
At 110k QPS, dropped packets at ~20k/s, bandwidth usage at 110~130Mbps, ntpd CPU ~70%.
I guess the suddenly increasing in dropped packets indicates that my server is not healthy. I wonder what should I adjust, or maybe some more info are needed to figure out the bottleneck? I have already disabled conntrack as other posts suggested.
Thanks for any help!
