I've been wondering this too. I'm now compiling 2.6.15 and would like to know which is the best Preemption Model for a dedicated MythTV box that runs both frontend and backend. In case it matters, I do use my MythTV box to record and play ATSC so my processor gets pegged pretty well.

Hi,<br><br> Just got as far as configuring kernel (2.6.13-rc6-git4) options for my<br>mythv system to be (I understand that the 2.6.13 release candidate is superior<br>to 2.6.12.x kernels). There are some new choices here, one of which is
<br>preemption model. Presumably aggressive preemption isn't great for things<br>like myth where a long running decoding task (for example) should be allowed<br>to keep using as much cpu as it needs at the expense of new processes.
<br><br>What does the list think? There now appears to be a choice of three levels<br>of preemption.<br><br>Any other recommended kernel options that should be included/avoided?<br><br>Cheers<br><br>Marius<br>Registered Linux user
