 * I really like the chat but I have to change to a custom built chat because the
   load on admin-ajax.php is so immense that it is able to take down the VPS. Response-
   time will always be a lot better after I deactivate the plugin.

 * Hi,
    Quick Chat is using long polling and long polling isn’t what you might call
   inexpensive to server performance but it is the only way to have self hosted 
   chat on shared hosting. Due to long polling Quick Chat isn’t meant to serve more
   then a few dozen concurrent chatters on an average server. If you are using VPS
   you should use XMPP based chat solution where you can install XMPP server and
   watch it fly, I guess that’s why you’ve taken VPS, to be able to add software
   your sites need. Shared hosting users don’t have that possibility.
