slf4j5 - Java logging even faster

In my previous posting where I introduced slf4j5 I reported that, to my surprise, performance was better than when using slf4j by itself - probably due to the usage of the Java 5 String formatter.

Inspired by this I took a closer look at performance and ended up creating a dedicated thread in each logger for doing the actual logging work (i/o). This resulted in more than a 50% improvement over slf4j5 without the dedicated thread. This has the added benefit of providing for non-blocking logging in a multi-threaded environment.
