I am pretty sure I generated them by using FilterPerformanceComparison. Today it uses a ThreadContextMap filter but I believe I swapped that out for a Marker filter to get the numbers on the web site.
BTW - How do I run one of the performance tests that are in log4j-core? I used to be able to do mvn test -Dtest=TestName but that no longer works.
