'idling' xbmc give over 50% CPU load?..
#1
Hi,

I've just accidentally ran across a peculiar thing: a seemingly idling XBMC (just fresh after the whole system boot up). The measurements taken half an hour after system restart. The 'top' under Ubuntu 8.04.2 shows that xbmc.bin is consuming over 50% of the cpu:

--------
Cpu(s): 55.6%us, 1.5%sy, 0.0%ni, 42.0%id, 0.2%wa, 0.3%hi, 0.3%si, 0.0%st
Mem: 3369600k total, 236220k used, 3133380k free, 6628k buffers
Swap: 4000144k total, 88k used, 4000056k free, 113428k cached

PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
5899 xbmc 20 0 152m 57m 37m R 60 1.7 6:27.03 xbmc.bin
---------

Do I misread the stats? Or can it be that my AMD CPU just dropped the frequency to 1Ghz due to low system usage (and hence, it's 50% not of 2.5Ghz AMD2 I have, but only of 1GHz)...

Try searching the forums. This has been covered a LOT!

Search for high cpu.
42.7% of all statistics are made up on the spot

Always read the XBMC online-manual, FAQ and search the forum before posting.
Do not e-mail XBMC-Team members directly asking for support. Read/follow the forum rules.
For troubleshooting and bug reporting please make sure you read this first.

Sorry - you are right. I thought it's an abnormality of my system. Will try first the fixes proposed in the other threads...

Ok, I got it down to 20% when idling and ~30% playing most of my videos (540x340).... The percentage is of assumingly 1Ghz (that's what the title XBMC screen shows for CPU frequency)

Can the idling CPU usage be brought down even further or that's pretty much the average number for most of the people?

Thanks,

Vlad

XBMC uses a game loop to handle rendering/input so that's about as good as you'll get. I see similar numbers when my CPU falls off to 800MHz.

Ok, cool. Now I only need to find the fix for the DVD issue (http://forum.xbmc.org/showthread.php?tid=45195) to enjoy XBMC to the full extent Smile.
