TSG-OS版本：24.07
|
||
现象：monit_stream -lHs发现firewall丢包，monit_stream -lHs --per-stream发现一个或多个线程稳定丢包，TOP查看cpu占用，单核占用50%左右，perf top查看丢包核没有明显耗CPU的进程

通过packet-io-engine hotfix已解决，观察24小时，泉州联通4台不再丢包
|
||
crudini --inplace --set /opt/tsg/mrzcpd/etc/mrglobal.conf service poll_wait_throttle_usleep_threshold 128

2024-10-23晚21:00，联通192.168.21.3再次出现该问题，重启packet-io-engine解决（这台tsg-os的packet-io已hotfix过了）

检查该站点的服务器BIOS设置，发现服务器工作在节能模式。由于节能模式有可能采用动态调频技术令CPU工作在低频模式下以节约电能消耗，因此建议调整BIOS设置，启动性能模式后再观察该现象是否仍存在。

联通21.1-2，23.1-2都在BIOS里调整电源模式为性能模式了，目前还有丢包的现象，但不是每晚都出现，观察监控11.02、11.03两晚23.1都丢包
