Overview Context switching imposes a performance penalty on threads in a multitasking environment. The source of this penalty is both direct overhead due to running the context switch code and indirect overhead due to perturbation of caches. Indirect overhead is calculated by measuring the running time of tasks that use context switching and subtracting the direct overhead. The indirect overhead impact is also measured on the running time of tasks due to processor interrupt servicing. Experiment results are presented for the Linux kernel running on an ARM processor based mobile device platform.
