Hi, I am planning to write a 1-1 voice chat application. I went through the samples and I think coding it is pretty easy using the NetConnection and NetStream bundles. However, I want to figure out various performance tuning measures required and what could be some best practices in terms of server configuration etc. to make this app work seamlessly in a production environment and also scaling the number of users shouldn’t be a problem? I would also like to know if there is any way to calculate the server configurations best suited to host wowza to do 1-1 voice chat with say 200 such rooms? Thanks. ---

First, tune the server: [https://www.wowza.com/docs/how-to-do-performance-tuning](https://www.wowza.com/docs/how-to-do-performance-tuning) Step 7 is specific to chat apps. For this type app, use StreamType “live-lowlatency” 1 to 1 chats should scale at least predictably, as compared to few-to-few or many-to-many chat applications, which don’t. Richard
