Hi Joern,

I'd speculate that the SimpleLogging variant would be at least a 1'000'000
times slower than invoking any existing slf4j logger. I'd be very surprised by
anything less than 100'000 but I like surprises.

To get somewhat "reliable" micro-benching results, I'd use System.nanoTime
before entering and after existing the loop, and run the loop 3 times (to let
the HotSpot compiler warm up) using the 3rd result. The loop length should be
inversely proportional to the speed of the code inside the loop (very quick
code => long loop length, slow code => short loop length).  

HTH
