iowait != cpu busy.  Your cpu idleness stays above 80%.

Ok ...... but one of my CPU core are at 99% usage ....
htop report this ....

So how to solve this problem ?

The red part of cpu usage bar represents 'iowait' not cpu usage. Fire up both top and htop and pay attention to 'Wa' value in top. You're just confused about how the graph is drawn in htop, nothing wrong with your system.
