title: Is it worthy to migrate quickfixj from Mina to Netty?
body: <p><br>
  I am writing a FIX buyside GUI based on quickfixj. Although the performance is not an issue to a GUI, I am thinking of migrating the quickfixj from Mina to Netty as I would like to develop it to a buyside engine.  The performance of quickfixj is not satisfied with me. It is heard that Netty is better than Mina on performance.<br>
  Does anyone know is there any other opensource FIX engine on Java platform(because of many bugs in quickfixj)?I am wondering which one is a better choice, migration or another FIX engine?</p>
