How to optimize Wowza server

How to optimize Wowza server for Peer5

If don't already have a running Wowza server please follow one of the following guides:

This guide assumes HLS is being setup. DASH integration is performed in a similar fashion.

In order for end-users to efficiently transmit segments a few configuration changes are required. The default number of segments, the segment length and the number of chunks can improve overall user experience and peer-to-peer performance.

The default Wowza HLS configuration value is to return 3 segments in each playlist - each 10 seconds long.
We’d like to configure it to 20 segments, 5 seconds long each instead.

Option 1: From the Wowza UI

a. playlist length
Under your live application > Properties > Cupertino stream packetizer
set cupertinoPlaylistChunkCount to 20

b. segment sizes
Under your live application > Properties > Cupertino stream packetizer
set cupertinoChunkDurationTarget to 5000

c. number of stored chunks
Under your live application > Properties > Cupertino stream packetizer
set cupertinoMaxChunkCount to 30

Option 2: Application.xml

It is also possible to set these values directly in the application configuration file located at /conf//Application.xml
Make sure to backup the configuration file in case anything goes wrong*

Open the file with a text editor, In the XML under Root/Application/LiveStreamPacketizer/Properties add the following properties:
