You should run the code at https://github.com/ceki/logback-perf <https://github.com/ceki/logback-perf>
to compare your results to Ceki’s.  You also should capture the cpubenchmark speed of your
processor and get the speed of your hard drive. I used Blackmagic speed test on my Mac. I
am capturing my results in a Google spreadsheet. I will post the like once I have it.
