The underscore? It does not do anything, this is just a valid part of the variable/type/field/function name.If you mean io_service_, acceptor_ and new_connection_ before the body of the constructor server::server and after ':' — they are field initializers, as well as thp. They are...

How can if-else statements be faster than std::map

At a guess: the strings "test1", "test2", "test3" are all very short and maybe the compiler is smart enough to use a "small string optimization", and ends up comparing 64bit ints rather than doing a string compare. You also have a very small...

You can determine the packet size, and implement a timer so that you don't send any more than 'x' bytes per second by counting manually in your program and watching the timer. If the data you are sending is reasonably large, you can estimate the packet size as roughly the number of payload...
