Wowza 4.0.1 starts very slow. I want to disable all new modules to speed up startup time. How can I turn off all new modules such as RESTServer, MediaCache[MediaCache] and others? ---

You can disable MediaCache through the UI under Server/MediaCache/Disable MediaCache, or by editing /conf/Server.xml and commenting out the MediaCache ServerListerner. Disabling the RESTInterface will mean you can not use the UI but it can be done. In Server.xml change ```auto true ``` To: ```auto false ``` and restart Wowza. Salvadore ---

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 > The Wowza Media Systems Software licensing system has determined > > that your license key is not valid.

As I far as I know, It is impossible to reload custom module without restarting wowza > [@Update custom modules without restarting Wowza](http://community.wowza.com/t/-/34311): > > 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.
