&gt;   RAM is not stressed: of the 1015MiB of RAM, 182MiB are free, and only 6MiB of swap is used. We typically don&#x27;t worry about RAM on Linux systems until the swap space used exceeds twice the physical RAM<p>That&#x27;s a bad metric. The question is rarely &quot;does this machine use too much swap&quot;. The problem comes when performance is degraded because pages that were evicted out to disk are now needed again, and those processes wait for I&#x2F;O. swapin and swapout are the relevant figures.<p>edit: (If you&#x27;re only using 6M of swap, it doesn&#x27;t really matter, of course. But if a system uses any substantial amount of swap, you want to check rate, not quantity.)
