hi *!
sorry to hijack this thread, but: when enquiring about latency tuning, one frequently encounters hints like "disable cron", "disable indexing services", "disable this, disable that".
however, none of those alleged culprits run with real-time privileges or access driver or kernel code which does. so how can they be a problem (and disabling them part of the solution)? i'm asking because i've got my own anecdotal evidence that it *does* make a difference...
i understand how device drivers can be nasty (graphics cards locking up the pci bus, wifi chips hogging the kernel for milliseconds at a time or worse...) but it seems that a) either kernel preemption and real-time scheduling is terribly buggy or hand-wavey, or b) we're feeding each other snake-oil in recommending to disable userspace things that is running without rt privs.
i'd love to be educated on this. best, jörn -- Jörn Nettingsmeier Lortzingstr. 11, 45128 Essen, Tel. +49 177 7937487 Meister für Veranstaltungstechnik (Bühne/Studio) Tonmeister VDT http://stackingdwarves.net _______________________________________________ Linux-audio-dev mailing list [email protected] http://lists.linuxaudio.org/listinfo/linux-audio-dev
