playbacking the tcpdump file is not stable

Asked by lx

I am glad to find the tool with a new version, but still leave a problem.
when I playback a size of 5GB tcpdump file , the tools is not stable. In MySQL, we can find that the QPS and TPS suddenly drop to zero after playbacking a some time. I find when have no QPS and TPS, the CPU usage of sys is higher than usual.
Use the tool "perf top", I find the spin_lock is higher than usual.

samples pcnt function

9753.00 31.8% _spin_lock

so is it a bug?

wait for your answer, thanks

As mentioned in my comment on the post, fleshing out the details on the bug report would be much appreciated: sample tcpdump that causes the problem (perhaps a smaller one can suffice, or generate one with other load generation tools), server version, OS platform etc.

Can you help with this problem?
