| Post subject: | R5A16 cpu usage increase |
After upgrading from R4V5 to R5A16 I noticed a large increase in cpu usage watching live tv. With the kerneldeint and quickdnr filters my cpu usage went from about 30% in R4V5 to 60% in R5A16 when using libmpeg2 (and a bit more when not using it). According to hdparm I have dma enabled for the drive. It appears mythfrontend is the only thing hitting the cpu hard. I don't notice any change when using mplayer or xine to watch videos. Is this normal? Anyone else notice anything or could there be something wrong with my setup? Thanks! rich |

I've noticed the newer versions of lircd seem to be using more CPU time for some reason... This may or may not be related. |

Did you remember to install the nvidia drivers? |

Yes, I installed the 6629 version of the nvidia drivers. I didn't install 7174 because I had some trouble with those on my desktop, though they could be fine on the myth box. Maybe I'll give those a shot. lircd doesn't seem to be using much cpu time. mythfrontend is using a lot of cpu. Top show it as the main user followed by either XFree86 or mythbackend. Actually I see lirc_dev is next. Hmmm. Thanks for the ideas so far! |
