[mythtv-users] Reducing system resources (cpu, memory)

I'm new at the mythtv thing, but here is what I have to say:

I have a PVR350 and it really does not use the CPU much at all for playback or 
encoding...  Takes a great deal off the CPU

Memory - myth is memory hungry, which in turn can cause you to go into 
swapping on the hard drive (bad).  This means that not only are you out of 
memory, your disk usage is also going off the deepend.

cat /proc/swaps
cat /proc/meminfo

This will show you how much is being used in swap.  If you are using a lot of 
swap then you need either less stuff in memory, or more memory.

One possibility is moving to a lighter desktop... for example, I use KDE on my 
notebook, but on my myth system I run fluxbox.  Takes up less of everything - 
disk space, compile time, and memory.  Not sure how much, but KDE does eat up 
alot.  I took a quick look and it seems like KDE uses 30MB more of memory...  
Someone could probably do a better analysis than me.  Anyway, if your low on 
memory that could help.
