Benchmarks (Log4j - Direct, Log4j - Using SLF4J, LogBack, System.Out)
Are there any recent benchmarks of these? I am trying to get some actual benchmarks as well as how they were computed showing the upsides/downsides of the logging systems. -Eric

Are there any more benchmarks for the appenders themselves? E.g. is logbacks rolling file appender faster than log4js... etc? -Eric Ceki Gulcu wrote:

Most of the code in log4j as well as logback were written by the same person. Thus, you can think of logback as log4j version 2.0. To answer your question, the way logback rolls files is more reliable, but it is not faster nor slower. Note that logback can automatically compress rolled over files. It does so asynchronously which can make a big difference for large files. In general, appenders should have the same speed, except for those serializing events on the wire which should be 10 times faster with logback. Eric Faden wrote:

I just ran these again with log4j-1.2.15, slf4j-1.5.2, and logback 0.9.9. I got these results on OpenSolaris 2008.05 in VirtualBox under XP with Java 1.6.
############################################### Log4j direct debug call: 681 Log4j tested (isDebugEnabled) debug call: 28 Logback direct debug call: 671 Logback tested (isDebugEnabled) debug call: 19 Logback parametrized debug call: 23 ############################################### The somewhat unusual configuration is due to the fact that I hope to use dtrace with one of our applications to get non-benchmark results on the same configuration. -- Thorbjørn Ravn Andersen "... plus...
