Does Logback use JNDI?
Logback-classic ships with a selector called ContextJNDISelector which selects the logger context based on data available via JNDI lookup. This approach leverages JNDI data separation mandated by the J2EE specification. Thus, the same environment variable can be set to carry a different value in different applications.

Is log4j2 better than Logback?
logback version 1.3-alpha10 performs about 3 times faster than log4j and about 1.6 times faster than log4j2 in case of synchronous logging. For asynchronous logging, logback 1.3 performs 2.5 faster than log4j and 2.3 times faster than log4j2.
Which is the best logging framework in Java?
