General Performance Tuning

elow are several suggestions for tuning Wowza Server on your production hardware. :

1. It is generally best to run the most recent Sun Java JDK (http://java.sun.com). 
   
   Note: If you are on a Mac with OS X 10.5.x or greater (Leopard) with 64-bit hardware you can run the Java 6 VM. To change your default Java VM in OSX, open the Java preferences application /Applications/Utilities/Java/Java Preferences and drag the Java SE 6 item to the top of the Java Applications list. More information here: Changing the default JVM on OSX Leopard
   
   
2. It is best to run a 64-bit operating system with the 64-bit Java VM. The 64-bit VM enables Java heap sizes greater than 2GB.
   
   Note: Wowza Media Server 2 will run properly on 64-bit Windows platforms.
   
   
3. The most recent development builds can be found here:

4. It is best to run the -server version of the Java VM. The instructions for configuring the server version is described in these two forum threads:
   
   Linux and OSX tuning, running the "server" Java VM (tuning)
   Windows tuning, running the "server" Java VM (tuning)
