AFAIK, it won't benefit audio/midi processing, it might even delay it slightly, but note slightly... It's purpose is to provide accounting information, that is to say to help profile interrupt handlers. I have it turned off on the archlinux -rt kernel as I try to track the distro's main kernel as closely as I can, and just enable or disable the few options that are really relevant to getting good -rt performance. -- Joakim _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
