The latency means the time after a task is invoked and before it is executed. It depends on Linux scheduler latency, the deferred execution method (workqueue vs. tasklet vs. kthread), and the priorities of competing tasks. In this talk , we show the effective ways to experiment the different methods, in terms of their response latency, and figure out how the system load, and user space task priorities affect them on both Intel and ARM architectures.

We will also analyze and improve the scalability of Linux performance in multi-core environments upon the measurements, used in actual real-time applications.
