#### High CPU Utilization
You can reduce CPU utilization by setting the environment variable with `set IPEX_LLM_CPU_LM_HEAD=0`.
#### Better Performance with High CPU Utilization
You could enable optimization by setting the environment variable with `set IPEX_LLM_CPU_LM_HEAD=1` for better performance. But this will cause high CPU utilization.
