The log4j-slf4j-impl binding is trying to be garbage-free, but the SLF4J API only offers up to two parameters for a parameterized message. More than that uses varargs which creates a temporary object for the parameter array. The native Log4j 2.6 API has methods for up to ten unrolled parameters. Another consideration is that the native Log4j 2 API lets you log Objects, not just Strings. Any Object that implements CharSequence can be logged without creating garbage. You can also implement the log4j Message interface if you want to separate formatting from your business domain objects. Finally, the native Log4j 2 API has support for logging Java 8 lambdas (since 2.4). > 2. when do you expect log4j 2.6 to be released GA i.e. ready for production > use?
