### Reproduction

```text
使用如下命令运行推理引擎时，即使再推理引擎没有进行任何推理引擎时，CPU也有两个核心占用为100%，导致CPU在待机情况下温度略高，请问是否有什么降低待机时CPU占用率的方法？

命令：

uv run kt run /models/MiniMax-M2.1/ \
--host 0.0.0.0 \
--port 9810 \
--served-model-name DeepSeek-V3.1 \
--max-running-requests 4 \
--tool-call-parser minimax-m2 \
--reasoning-parser minimax \
--kt-method FP8 \
--kt-cpuinfer 40 \
--kt-threadpool-count 2 \
--kt-num-gpu-experts 8 \
--chunked-prefill-size 12288 \
--max-total-tokens 50000 \
--kt-gpu-prefill-token-threshold 2048 \
--log-level debug
