Hello, I would like to ask the author, what is the cause of the log content? Is it the operator's qos?
Thanks！

I had tested. My home network provider is cmcc,my parents network provider is ctc. I tested with my cellphone which has both two provider.when the network in cmcc,the streaming is very smooth，when the neiwork switch to ctc,the streaming became very laggy. It seem like qos between two providers.

please help me check the config file,see where was wrong or which can optimize,thanks.

1. Performance tip: do not enable fBindToCPU if you set threadsCountMax to small number.
2. fCacheGetTimeSyscall and timerGranularity was removed.
3. In case 4k+ resolution or any other hi bitrate content ringBufSize should be 4096+.
4. precache =< ringBufSize, it is cosmetic tip.

How msd_lite connected to both your ISP~s?

Thank you for your professional advice. I will test it later.
I use msd_lite by binding the domain name to ipv6 address.
