title: Speed of json-rpc in C++
body: <p>I'm using json-rpc-cpp library from <a href="https://github.com/cinemast/libjson-rpc-cpp" rel="nofollow">cinemast</a></p>
  
  <p>As a test I have written simple server which takes two integers and returns their sum to the client.
  On a really small VPS (128 MB RAM) it was possible to reach ~270 queries per second on localhost and then on two separate VPS's.</p>
  
  <p>Is such a result standard for json-rpc? Can I make it noticeably faster?</p>
