Maybe someone in this mail-list does tests to determine whether or not<br>

Hello everybody,<br>
<br>
Alessio, Tim, I fail to understand this sudden position shift towards -lowlatency. Half a dozen users tested the -lowlatency kernel this summer, with the following results:<br>
- Yes, lowlatency provides noticeably lower latency than generic<br>
- Rt/realtime remains snappier and thus remain a requirement for diehard audio users needing top notch performance.<br>
- However, rt/realtime are very painful to maintain compared to lowlatency that consists in "simple" build-time tweaks<br>
<br>
This resulted in an apparently well-accepted *focus on lowlatency for Natty*, summed up by Scott in end-of-September emails. We even nailed it in <a href="https://wiki.ubuntu.com/RealTime" target="_blank">https://wiki.ubuntu.com/RealTime</a> , including a testing table featuring two neat green "lowlatency" rows.<br>
<br>
Alessio, don't get me wrong here: I respect this amazing work you've been doing (and that I'd totally be unable to do), I know you are doing it alone, and I know the absence of feedback can get discouraging.<br>
I just want to understand why this question pops now. We should be pushing for inclusion in Natty, and instead of focusing on testing and bugfixing we are re-debating an already closed subject.<br>
<br>
Anyway, *yes there is ongoing testing*: right now holstein, ailo, I (and possibly other users) are testing it. Again:<br>
Testers: please keep hammering the lowlatency kernel from Alessio's PPA, and report your test results.<br>
Alessio: please bear with us and continue your efforts, rest assured the interest is there.<br>
<br>
I hope this email doesn't sound harsh. No aggressiveness intended, I only mean to be synthetic and to the point. Thank you,<br><font color="#888888">

Meh. Will try again to test lowlatency in a few days.</div>
