Thanks, Salvadore.

I am developing custom module. So I want to speed up restarting wowza on my local machine.

When I used Wowza 3.5.0 restart time takes about 8 seconds.

Now Wowza 4.0.1 with only one small application takes **26 seconds** (!!!)

If I turn off RESTInterface Wowza cant start because it cant validate license

How else I can speed up restarting time?

As I far as I know, It is impossible to reload custom module without restarting wowza

> Dear Wowza, I am Flash/Java programmer working on platform for audio/video/text chat. We have few wowza application running on server, each one with its own custom made module. I am curious if there is any way how i can update custom module classes (jar file inside lib/ folder) without need to restart Wowza media server. After i did few tests, it looks like Wowza red this classes when server was started and didn’t get any changes of jar files later. Thanks for help.
