Title: Kernel Object Performance Description: The app_kernel test is used to measure the performance of the following kernel objects: message queues, semaphores, memory slabs, mailboxes and pipes. When the userspace version is selected (CONF_FILE=prj_user.conf), this benchmark will execute with four configurations (kernel/kernel, kernel/user, user/kernel and user/user). However, any configuration involving user threads will omit both the memory slabs and mailbox tests. -------------------------------------------------------------------------------- Sample Output:
