 ## Functionality
-A thread is created for each command* entered. There is a kind of waiting loop for these commands, so **only one connection can be executed at a time per id**. So if you make 4 get commands, these are processed **one after the other**, which means that the _last command is executed much later_ or if you make 4 get commands, half id=0, half id=1, these are processed **2*one after the other**, which means that the _last command is executed a bit earlier_ .
