<div dir="ltr">i can corroborate swap slogging and thrashing has long been a problem for both firefox and chromium, my way out has been to merely quit the browser and relaunch, and seethe under my teeth wondering whether to blame the horrible memory management on the kernel, browsers, libraries, or what. on the other hand just a couple days ago i watched in amazement as firefox actually released a ton of swap while i continued browsing. maybe somebody is actually hip and incrementally improving something?<br><br><div><div class="gmail_extra"><br><div class="gmail_quote">On Mon, Sep 18, 2017 at 4:26 PM, Jeff Chapin <span dir="ltr"><<a href="mailto:chapinjeff@gmail.com" target="_blank">chapinjeff@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Swapoff checks that automatically -- but I usually do it when I notice that I am using a ton of swap, but not all my ram.

<p>Do you check to make sure your existing swap usage and RAM usage combined does not equal a number higher than the amount of total RAM you have on the system? I am guessing flushing swap into RAM when there is not enough RAM available is a bad thing to do.<br><br>Just curious, why do you clear your swap space like that periodically? If your swap is being used too much, perhaps you either need more RAM or else should maybe turn down your vm.swappiness in sysctl.<br><br></p><div><div class="m_7338187521213981986h5">

<div>I periodically check swap usage, and run:<br><br>sudo swapoff -a; sudo swapon -a;<br><br></div>
This will force anything in swap (on disk) back into RAM.<br><br></div>
