title: high performance rtsp server
body: <p>I want to implement a high performance rtsp server which is to handle vod request --- it only handles signaling request, it does not need to streaming the media file. I have accomplish a version that is written in Java basing on the Mina networking framework, and the performance seems to be not very high. </p>
  
  <p>As far as I know, high performance SIP server(e.g. VoIP server) is written in C (e.g. OpenSIPS, Kamailo), should I use C or C++ for my project to get a significant performance improvement?</p>
  
  <p>BTW. I found some explanation of the reason why OpenSER is written in C by its author:
  "On the other hand, it is the garbage collector that can cause lots of troubles when developing SIP applications in Java. Aheavily loaded server written in Java stopsworking when the garbage collector is cleaning the memory. The delay caused by the garbage collector can be even more than 10 seconds. Such delays are unacceptable"
  Is that a fact nowadays which mean that I should use C too?</p>
