The question is completely meaningless and impossible to answer unless you specify what exactly you mean when you say "performance". Operating systems do lots of things, including in userspace. The answer to your question could be how a userspace library handles many small files being read concurrently, or how the network stack works, or a hardware accelerated UI animation, or sound mixing latency, or memory allocator implementation details. |
