title: epoll_wait on several Threads faster?
body: <p>I am thinking of programming a tcp server based on <code>epoll</code>. 
  To achieve the best performance i want to implement multi core support too. But during my researches the following question came up:
  Is it faster to call two <code>epoll_wait()</code>-Calls from two different threads, each observing their own file descriptors on a dual core? Or is this as fast as calling just one single <code>epoll_wait()</code> which observes all file descriptors?</p>
  
  <p>Since the Kernel observes the file descriptors, i think it doens't matter how much threads i use on user space calling <code>epoll_wait()</code>?</p>
