I'm trying to find out the name of the local machine (or some other way of uniquely identifying a particular machine) that an application is running on.

I've been using this:

```
String hostname = java.net.InetAddress.getLocalHost().getHostName();

```

which works fine, but I just happened to notice in the profiler that it's taking quite a bit of time to execute that so I was wondering if there was something functionally similar that ran more quickly.

Doesn't have to be host name, could be anything as long as it uniquely identifies the machine.
