I have 512 MB of RAM in my Myth box (combined BE/FE, dedicated machine), and NO paging space allocated. This greatly reduces the amount of paging. ;) Only problem I've ever had was due to the OpenGL memory leak in MythGallery. Other than that I've never had any problems with running out of memory. aaron ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

I don't think myth really needs the large diskcache (over 150MB) that gets created. Or am I wrong on that? ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
[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 M1 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? ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
RE: [mythtv] [mythtv-users] Swap optimization
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. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Asher Schaffer Sent: Sunday, January 02, 2005 5:28 PM To: MythTV-Users Subject: [mythtv] [mythtv-users] Swap optimization I'm curious what people have done about memory optimization in their myth boxes.

When running top if you press M (it needs to be a capital M not lowercase) it will sort the processes by memory usage. ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
