[LAU] : jack CPU % is going crazy !

[Mysth-R]

 Hello list,
Since I have installed Gentoo I got some issue with JACK. I am using Jackdmp
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%  ...

I don't understand very well what it is going wrong.
My config :  gentoo 64 bits version on a Dell Insprion 9400 Intel Core Duo 2
T7200 with 2 Go Ram.
Firstly I had installed jack 0.109 and the issue was worse that jackdmp
:sometimes CPU load until 80%

The kernel I use was compiled by my own. Perhpas I forgot an option or
something...

uname -a  :
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


Thank you very much for your help.

Cheers,
Mysth-R
