[mythtv-users] Memory Consumption

[Ken Thompson]

Are you running an onboard video card that uses shared memory?

I see the same behavior.  Also running on 256 (RDRAM) on a P4 2.4 Ghz
with Mandrake 9.1 and PVR-250.  
 
I notice freezes every now and then, which require the application to be
restarted.  I also notice that if I leave it on live TV for a while (few
hours maybe) then Myth seems incredibly slow to respond.  For instance
if I hit the back button at this point (from live TV) it responds a
couple seconds later, and the screen refreshes very slowly.  I don't
have the memory/CPU usage stats but I'll try to gather them soon.
 
I wasn't sure if this was somehow specific to my particular machine and
setup, therefore I didn't write in to the forum.
 
I'm building a new machine soon for Myth which will have 512 megs, it'll
be interesting to see how it compares.

Ok, it seems as though I have been able to isolate some memory problems.
Somewhere in the documentation, mythtv or ivtv said it needs atleast 256
MB of RAM.  This is a BARE minimum I found out the hard way.  Just
running mandrake 9.1 with KDE + the mythfilldatabase I am burning a
whopping 218MB of ram + 14-35% processor time.  With my onboard video
enabled (64 MB of shared memory. yuck) I get random pauses during live
TV playback.  Its obvious 512 or > is required to run this program
correctly.  Btw, I've got a duron 800 (utter crap, I know) with 256 MB
ram/ Hauppauge 250
 
This may be old news to lots of you, but I thought it was worth sharing.
