you need -rt. "
every.single.time.
without rt, the packages I use are virtually useless. performance sucks.
with rt, a world of good.
it always amazed me that redhat never let Fedora into their 'real-time' kernel plans. would have been great if fedora was bleeding edge for that now.

and suck it up, but that obviously takes us further from our 'upstream first'
mantra.
Ingo & Thomas are getting sizable chunks of it merged upstream, but I don't think
we'll be seeing it all merged soon, but then again, F10 is quite a ways off,
and with a few more kernel releases, who knows.
Depends how objectionable the remaining bits are I guess.
Given that so many people are now distributing products based on this work, getting
it all in mainline is obviously important, and there's no shortage of manpower
helping drive it there.
All this said, I personally haven't hit any issues with things like MIDI in
Fedora where the -rt kernel would have helped me. Maybe my gear is special,
but latency between me hitting a key on a synth and having that note show
up in rosegarden, and a sound being created is well below perceivable.
I'm interested to hear any test cases you guys may have that justify why
you need -rt. Right now the guys working on that stuff typically have a
bunch of 'boring' test cases more tailored towards replicating situations
like stock trades and the like. If we can construct additional use-cases
I'm sure Ingo, Thomas & co would be very interested to hear about them.
Especially if these cases are triggering different latency paths.
