Pick low-hanging fruit¶
Merely enabling Real-time Ubuntu doesn’t optimize the kernel for your application. Tuning may be helpful, for example to reduce cycle-times and other latencies. Real-time Ubuntu offers various configuration options and boot parameters for the purpose.
Treat tuning techniques as a toolkit, to choose from according to the demands of your application and the environment it runs in. At each step, apply the most important and readily available improvement. An early candidate is the kernel’s task scheduler.
