MQX/MQX Lite Context Switching Cycles

Does anyone know the amount of cycles it takes to perform a context switch in MQX? Is MQX Lite any different?

Hello,

this thread gives you a hint which example to check and david shared also there some numbers:

Quoted from MQX Real-time Operating System

Depending on platform and options chosen, MQX RTOS can be configured to take as little as 6K bytes of ROM, including kernel, interrupts, semaphores, queues and memory manager. MQX RTOS delivers the performance that demanding customer have come to expect in leading RTOS solutions as well, on a 200 MHz PowerPC® MPC8248, interrupt latency came in at 0.331 µsec and context switch time was benchmarked at 0.558 µsec.
