Comment 13 for bug 2051342

The generic Ubuntu kernel has dynamic preempt enabled. This allows the preemption model to be changed at runtime between: none, voluntary (the default), and full.

It would be super interesting to test what impact this has for latency sensitive workloads, and whether this can help you make the lowlatency kernel build redundant.
