There might be an issue you want to check into.
First of all, I love this app! However, if I put this as a block on my website, it causes the webpage to load very slow.
It goes from approx. 1 second loadtime without the block, to around 10 seconds with the TS3 integration added as a block.
This load time only happens on web pages that has the TS3 block displayed on it.
Another issue I ran into is whenever TS3 Integration is enabled, over time it will start A LOT of instances of CGI / FastCGI and causes the CPU usage of my dedi server to stick around 100% until I shut down the website, turn off the CGI / FastCGI instances on the Task Manager.
I, unfortunately, ended up completely disabling TS3 Integration due to these issues as it made my website unstable.
