I haven't heard much about ulatencyd in a long time. What's the current status?
I'm using it on Precise, and with the BFS and BFQ schedulers on the pfactum kernel patchset, but I'm not sure if it's still useful or necessary. Maybe I need to run without it for a while and see if I notice a difference.

Hello Adam,
Ulatencyd has been stable and intact for the past 6 months or so
because it doesn't seem to need any further tweaks. In addition,
ulantencyd author Daniel Poelzleithner has been busy with
higher-priority projects recently.
Ulatencyd is still relevant despite any patchsets because kernel
implements only mechanisms and ulatencyd provides policy for those
mechanisms. To put it simply, it lets your schedulers know which
processes are more important and which are less important so they can
distribute CPU and I/O shares smarter.
Default ulatencyd configs shipped in Ubuntu Precise are not very
useful on Unity. I've written configs for Pantheon and Unity shells
and generic Ubuntu stuff, but they are not available in Ubuntu yet.
You can install "ulatencyd-configs-elementary" from
https://launchpad.net/~elementary-os/+archive/testing to get those
configs in Precise.
