I'm using ULE now, and I see mysqld could use 104%in WCPU.

But do you know why services still share the cpu0 instead of using CPU1

PID USERNAME  THR PRI NICE   SIZE    RES STATE  C   TIME   WCPU COMMAND
  598 mysql      16  44    0   639M   633M ucond  0  50:53  4.83% mysqld
  740 services    3  44    0 54292K 51352K select 0   3:08  0.00% services

I wish kernel can balance using both CORES with ULE 2.0
