[mythtv] [mythtv-users] Swap optimization

[Byron Williams]

I hate to admit it, but I have no idea. I don't have a clue how to check CPU
usage or ram usage. I'm very new to Linux and I'm using Fedora core 2
following Jarod's guide. If I knew how to check I might be able to chime in.

Subject: [mythtv] [mythtv-users] Swap optimization

I'm curious what people have done about memory optimization in their
myth boxes.  I'm running a combination FE/BE on an EPIA M10000 with
512MB of RAM, so keeping things clean is rather critical to keeping it
all usable.  That said, I am running Azureus on this machine as well
which can be a huge memory hog, not to mention it causes a huge amount
of disk caching to occur.  Combine that was something like commercial
flagging and show recording and I have a huge amount (IMO) of swap
space being used.

At the moment I have 44MB of free memory,  7MB of buffer, 322MB
cached, and 80MB swapped.  The swapped space easily goes up to 180MB
at times.  I know there has been a lot of discussion on kernel lists
about vm.swappiness, I currently have mine set to 40, but I could turn
it down.

I guess this post doesn't entirely have a question, I just wanted to
open a discussion of what behavior people are seeing on their systems,
does it seem like mythfrontend is getting swapped to disk after being
inactive for a while?  And if so, is it causing a noticeable delay
when someone tries to use it again?
