I've installed mythbuntu 9.10 on 2 frontends and 1 backend. When a frontend is left alone for an extended period of time and I go to press a button on the remote it takes 30-45 seconds to revive. Once fully awaken and refreshed the frontends performs fine without delays. Is there some kind of low power mode the frontends are entering and how do I turn it off?

I guess as recordings happened Linux swapped out the FE process to make more room for disk cache. Anyway, I fixed my problem by reducing the vm.swappiness value in /etc/sysctl.conf.<br>
<br>The line (I had to add) looks like this:<br>vm.swappiness=10<br><br>The Ubuntu default is 60. You can check your current swappiness value by:<br>cat /proc/sys/vm/swappiness<br><br>I think you can also change the value on the fly with:<br>
sudo echo 10 >> /proc/sys/vm/swappiness<br><br>BTW my Mythbuntu 9.10 machine is set at the default of 60 as well.<br><br>Cheers,<br>James<br><br><br>
