<dl>
<dt>Install only the relevant files</dt>
         <dd>
         <p>Select only test related files when installing the operating system,Such as the compiler and library files.
         So that many services are not installed,this will reduce the consumption of resources by the operating system itself.
         </p>
         </dd>
         
<dt>HUGETLB_MORECORE</dt>
         <dd>
         <p>Set this environment variable to "yes" to enable applications to use large pages.</p>
	 </dd>

<dt>LD_PRELOAD=/usr/lib64/libhugetlbfs.so </dt>
         <dd>
         <p> Setting this environment variable is necessary to enable applications to use large pages.</p>

<dl>
 <dt>Hardware Prefetch:</dt> 
        <dd>
         <p>This BIOS option allows the enabling/disabling of a processor mechanism 
         to prefetch data into the cache according to a pattern-recognition algorithm
         In some cases, setting this option to Disabled may improve performance. 
         Users should only disable this option after performing application benchmarking 
         to verify improved performance in their environment.
         </p>
         </dd>

 <dt>Adjacent Sector Prefetch:</dt> 
        <dd>
        <p>This BIOS option allows the enabling/disabling of a processor mechanism 
        to fetch the adjacent cache line within a 128-byte sector that contains the 
        data needed due to a cache line miss.
        In some cases, setting this option to Disabled may improve performance. 
        Users should only disable this option after performing application benchmarking 
        to verify improved performance in their environment.
        </p>
        </dd>

<dt>Intel Turbo boost Technology:</dt> 
	 <dd>
	 <p>Enabling this option allows the processor cores to automatically increase its frequency and increasing 
       performance if it is running below power, temperature.
       </p>
       </dd>       
	 
<dt>Intel Hyper Threading Technology:</dt> 
	 <dd>
	 <p>Enabling this option allows to use processor resources more efficiently, enabling multiple threads to run 
       on each core and increases processor throughput, improving overall performance on threaded software.
       </p>
       </dd>
                       
<dt>Power Efficiency Mode (Default=Custom)</dt>
         <dd>
         <p>Values for this BIOS setting can be:
         Efficiency: Maximize the power efficiency of the server,Performance:Maximize the performance of the server,
         Custom:Allows the user to customize power and performance related options individually.
         </p>
	 </dd>
	 
<dt>cooling Configuration</dt>
         <dd>
         <p>This feature allows the user to adjust the fan speed manually,If the server is in a stressful environment, 
         the CPU have high temperature, you can adjust the fan speed to 100%.</p>
