How to use epoll? A complete example in C - Banu Blog
Network servers are traditionally implemented using a separate process or thread per connection. For high performance applications that need to handle a very large number of clients simultaneously, this approach won't work well, because factors such as resource usage and context-switching time influence the ability to handle many clients at a time. An alternate method is to perform non-blocking I/

For a definition of the term coroutine see The Art of Computer Programming by Donald E. Knuth. Coroutines are a very simple cooperative multitasking environment where the switch from one task to another is done explicitly by a function call. Coroutines are a lot faster than

Lock elision in the GNU C library
January 30, 2013 This article was contributed by Andi Kleen elision : the act or an instance of omitting something : omission Contended locks are a common software scaling problem on modern multi-core systems. As more cores are added the synchronization overhead increases, potentially exceeding the speed-up provided by the extra processors. Writing good, scalable, fine-grained locking is difficult
