I have tried it, but it didn`t help me very much. The program was in a
normal state in which it processed a packet.
I realized now that just before my program uses all CPU time the system
starts to use the CPU more.
The System uses about 30 % of the CPU and then my program starts to burn CPU
power. 
I think there is something happening in the kernel... ?
