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
