No true, it is just not set. I change mine to "low latency
desktop". Also the "Timer frequency" in the defaults SuSE kernek is set
to for server use. You should change it to either 300 Hz (for a balance if

| General Setup:
| Disable "Optimize for size"
| Disable "Control Group support"
| Disable "Group CPU scheduler"
| Processor type and features:
| Enable "Tickless System (Dynamic Ticks)"
| Enable "High Resolution Timer Support"
| Choose your CPU type in "Processor family"
| Choose "Preemptible Kernel (Low-Latency Desktop)" as "Preemption
| Choose "1000Hz" as "Timer frequency"
