title: Is a process faster when running in kernel mode than running in user mode?
body: <p>I've read that <a href="https://stackoverflow.com/questions/2354125/difference-between-processes-running-in-kernel-mode-and-running-as-root">post</a> and would like to know, if a process/program is running faster in root/kernel-mode.
  Currently I think that it must be the case, because of not going through those OS-rings (user- to kernel-ring) during the cpu-execution. Am I right ?</p>
