Yes, that is quite a strange recommendation and the recommendation of &quot;until the swap space used exceeds twice the physical RAM&quot; is really crazy.  The best recommendation for production servers is to disable your swap&#x2F;page file completely then just let your entire system crash on OOM.<p>Often times it&#x27;s better to have a dead system (you do have HA and auto-failover, right?) than to let difficult-to-track-down &quot;slowness&quot; into real time systems.
