Hi, and thank you for your answer.<br><br>I am actually trying qjackctl 0.2.23 and the problem is the same. So it should not be a QT problem.<br>Anyway, I can note that for the same qjackctl config the cpu load percent is lower on version 0.2.23&nbsp; (~= 2.5 - 3%) than on the 0.3.2 version (3 - 4.5%).<br>
<br>If someone has anonther Idea ... :)<br>Cheers,<br><br>Mysth-R<br><br><div><span class="gmail_quote">2008/4/5, Russell Hanaghan &lt;<a href="mailto:hanaghan@starband.net">hanaghan@starband.net</a>&gt;:</span><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">

  Hello list,<br>
Since I have installed Gentoo I got some issue with JACK. I am using Jackdmp<br>When I run qjackctl all is right but the CPU percent, in spite of staying around 3 or 4% it is moving : 4% then 3 %, then it passes to 27% then 10% and 53% and 4%&nbsp; ...<br>


<br>I don&#39;t understand very well what it is going wrong.<br>My config :&nbsp; gentoo 64 bits version on a Dell Insprion 9400 Intel Core Duo 2 T7200 with 2 Go Ram.<br>Firstly I had installed jack 0.109 and the issue was worse that jackdmp :sometimes CPU load until 80%<br>

<br>The kernel I use was compiled by my own. Perhpas I forgot an option or something...<br>
<div dir="ltr"><pre>uname -a  :<br>2.6.24-rt1 #4 SMP PREEMPT RT Sun Mar 16 21:42:41:CET 2008 x86_64 Intel(R) Core(TM)2 CPU T7200 @ 2.00GHz GenuineIntel GNU/Linux</pre></div><br>
Thank you very much for your help.<br>
<br>Cheers,<br>Mysth-R<br>
