I am still new to a lot of this stuff, and I searched back a bit through the archives (manually, as I don't know of a search functionality) to see if there was any discussion about it. First question, /proc/sys/vm/swappiness. Is there an advantage to setting this to anything than the default for my distribution, which is 60? I have heard that settings of either 100 or 0 are good for different reasons, but strictly thinking in terms of using my system for music production, what would you recommend? Second question, elevator=cfq. I am thinking that CFQ is not good for music purposes. Would that be correct? I've read it speeds up general desktop usage, but this might work against realtime-preemption, wouldn't it? Third question, ReiserFS vs Ext3 vs XFS vs JFS etc. Is there a filesystem that should or shouldn't be used with realtime-preemption? Fourth question, CONFIG_DEBUG_DEADLOCKS. DeMuDi has it enabled, but it gives a warning when you boot up that it could introduce higher latencies. Is it safe to turn off? I'm sorry if these have been asked before, but I didn't see anything. If you want to just link me, that's fine, I checked on Google and got conflicting results, and not a lot specific to music production. Thanks in advance. Dana
