Remember, this is not a dedicated CNC computer, this is a multi-user, multi-tasking, general purpose operating system. At the command prompt, do : ps xa and you will be AMAZED to see how many tasks are running, I see 164 on my system. All real-time parts of LinuxCNC are locked in memory when they start, but in the sim version, they are all capable of being swapped out, or causing page faults. The non-real time part of LinuxCNC is always capable of being swapped or paged.
