Affinity Questions

[bigo93bronco]

Ok, so I recently upgraded my server to a quad core (Q9550) and I have discovered that there are plenty of programs out there now that can automaticaly set affinity and priority for processes which you specifiy. What i'm thinking of doing, is assigning the sagetv service to core1, the sage media player to core2, the sage transcoder to core3, and comskip to core4. Is there any reason I shouldn't do this? How high can I set the priority for each? (this is a dedicated sage only server)

Personally, I've found that Windows is perfectly capable of handling the affinity of programs without my own meddling. Maybe there are valid scenarios where manually setting the affinity is helpful, but I steer clear of it myself.

hmmm,

I get what your saying, I just figured since sage isnt threaded, splitting up the different exe's onto different cores might not be a bad idea.

What benefit would that give you? What do you hope to accomplish as Sage uses very little cpu to begin with? Most of the time the Sage server sits Idle waiting for connections, recording or client requests.

Just to make sure there arent any slow downs while browsing menues, etc under max conditions. My setup will often see X6 recordings+X1 transcoding to placeshifter+ 2-3 instances of comskip running

Any issues you see with the 6 recordings will most likely be due to disk bottlenecks, not CPU. The others are certainly both disk and CPU intensive, but with 4 cores you'll probably be fine.

If I were in your shoes, I'd let Windows do its thing first and see how that works. If you do see a bottleneck isolated to the CPU, then give the affinity adjustments a try.

allright,

I'll just leave well enough alone then thanks for the advise

For what is worth, everyone here is correct, I am running Sage on a quad core with 8gb ram. Extreme over kill, the box never even ramps up with 5 clients streaming and the server recording.

Good luck with your new build.
