On a side note: Does anyone have any factual

config_irq_time_accounting ? I noticed that it increases the cpu

working on a custom kernel config and trying to document how each
parameter change affects audio and midi performance for later
publishing.
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.
