It depends on how low you want latency to go, but i'm one who sometimes thinks the 'obession' with ultra low latency is a bit self defeating. I sat in an orchestra for some time (woodwinds), and experienced quite a bit more than 5ms latency between me and the 1st violins. One learns to compensate. Maybe with 10-15ms latency, and a bit of 'instinctive user compensation' the end result may be better than one would think. Having said this, on 64bit Hardy UBStudio, i'm writing with an average of 8-10ms (non-live. I write in the box, so to speak), and on my new Debian 5 32bit build, with a self baked RT kernel (2.6.26-rt11), i'm getting 5-10ms dependent on task, comfortably, and importantly, with all day everyday stability. Previous testing, and i say this from a strictly personal perspective, had Gutsy UBStudio yielding the best results, with latency (tested for the fun of trying) as low as 3ms (stable). My soundcard is an Maudio Delta 44, with the ice1712 Alsa module. I don't use oss at all, and turned it off in the debian kernel build. I use raw as the midi driver, and a2jmidid for any cross alsa/jack midi requirements. limits are: audio nice -19 rtprio 99 memlock unlimited pidirq for the soundcard is set at a priority of 92 jack priority is set to 89 the computer is an AMD dualCore x64 5600+ with 4gb of ram. 3 HD, being 1 system, and two dedicated sample drives. Additional external drive for backup. All 7200, 32mb cache. Maybe something you see in this might help. *Note* In the settings you provided for jack, i notice you don't have a defined priority number for realtime, just an -R flag. Is there a reason for this?

I did want you to know, though, that rt has in the past run great with wine using Dragon NaturallySpeaking. As soon as the Creative X-Fi sound drivers are available without my having to compile them, I intend to try rt again. Maybe there's a niche market with a super-fast kernel with limitations: no compile, no big downloads.
