I ran the CXF build like: mvn -Pfastinstall -T8 -o
using the latest on the two branches as of 11pm last night: 3.0.4: 1:16 log4j2: 1:12 logback: 1:19 Ran each 3 times and results were fairly consistent. Thus, for me using parallel builds, log4j2 is the fastest, but the difference is almost irrelevant. I'll repeat the tests later without the -T8, but this may show that multi-threaded logging is faster with log4j2.
