TechARP's BIOS Option Of The Week is CPU Latency Timer, you can learn about it over here.
This BIOS feature allows you to control how the processor should handle a deferrable processor operation when there is a new request for the processor. By default, it is disabled.
When disabled, the processor will immediately defer all deferrable operations when there is a new processor request.
When enabled, the processor will defer those operations only after they have been held in a Snoop Stall for 31 clock cycles when the new processor request arrives.
It is recommended that you enable this BIOS feature to ensure that deferrable operations are given sufficient time to complete. This improves performance by allowing deferrable operations to be processed without excessive delay.
